AngularJS, developed by Google, is an open source structural JavaScript framework. It is the best used for building web apps as it is dynamic, and helps create Single Page Applications by just using HTML, CSS and JavaScript.

Angular is extensively used for developing responsive web designs that will make the web application usable with many devices.

Why is AngularJS the best and beneficial?

Developers save time as they don’t need to code an entire application as AngularJS is derived from HTML. This lets the developer to focus on functionality. The code is testable and the code as well as the components of the code can be reused which profusely reduces work. The below are the efficient features AngularJS possesses.

Two-way data-binding:
The two-way Data Binding is a brilliant feature in which any change made in the view will reflect in model and vice versa for a responsive experience.

Directives:
These are extended HTML attributes. You can custom the directives.

Client side MVC framework:
For an incoming client request in AngularJS, the response is in the form of JSON data and it makes the web application manageable.

Dependency Injection:
The Angular injector subsystem that is available is entitled for creating components, resolving their dependencies, and as well providing them to other components as requested. By resolving dependencies the work load on the backend is predominantly reduced.

Filters:
You can easily define your own filter for the display of the user which can be viewed as templates, controllers or services.

Expressions:
Expressions will bind Angular application data to HTML elements and display the result exactly where it is located.

Scope:
Used to access the view value in controller. There are JavaScript functions that are bound to a particular scope.

Usecases of AngularJS:
AngularJS can be used where there’s increased work load. It uses an ultimate approach where, API will be in a stateless server and UI will exchange the data with your server in JSON format, by which both ends can be decoupled.

When there are a lot of updates need to be made often and dynamically, Angular is the best. Angular paves a trouble-free way to do it than DOM manipulation frameworks can.

The Single Page Application leads to rational and maintainable way of AngularJS.

Build AngularJS Web Apps and Websites

The Guardian:
The Guardian is a British daily newspaper known for its design in publishing arena. UI of The Guardian website is developed as an AngularJS app.

Video Streaming Apps:
It suits well for apps that are especially used by millions.

Example: Youtube for PS3

User-Review Applications:
We would definitely want to know about that something before we go for it. Be it a product we are going to buy or any movie to watch. We are very much interested in the reviews and sceptical about it. We would want to know about it to make a wise decision. There helps AngularJS with user review applications.

Example: GoodFilms, that provides reviews.

Lego:
We all would have heard about this. It is best known for the manufacture of Lego-brand toys, consisting mostly of interlocking plastic bricks. It uses Angular’s single page application.

Travel Apps:
The dynamic features are perfectly suited for travel apps as they are very sought after.

Example: JetBlue

Weather Apps:
Everyone would be worried if it rains all of a sudden when we are driving. But we can plan and escape from it if we behold forecasts. The weather should be updated at frequent intervals which is essential for any weather app.

Example: Weather.com

User Generated Content Portals:
As AngularJS can handle tons of posts, projects, updates and chats every second, it is extremely compatible for portals like Freelancer.com and Upwork.com. Both use AngularJS as their basis.

Walmart:
Walmart, is an American multinational retail corporation that operates a chain of hypermarkets, discount department stores, and grocery stores. The amazing features and experience you receive is because of AngularJS

E Commerce and M Commerce:
Many leading commerce market sites are built by the use of AngularJS.

Example: Paypal

Newyork times: loads of news every day but still a its a reliable website. It is definitely because of AngularJS. Here also Single page application is used.

Social Apps:
Every professional is on LinkedIn. It is famous with everyone as it is easy to know about a person and his/her interests. When you view a profile he/she also gets notified. LinkedIn for mobile was built with AngularJS.

You may have a workbook which contains text but you only want to extract certain characters from it. For example, you may only want to extract the first name from a cell which contains the first and last name of a person. In this tutorial I will show you how to manipulate text and in particular, I will show you some great techniques on how to remove the first 4 characters in Excel using the following functions:

1) Excel RIGHT Function

2) Excel MID Function

3) Excel REPLACE Function

Using the Excel RIGHT Function
In this example I want to remove the first 4 characters from the postcode CV36 7BL and leave the last 3 characters. Let’s assume the postcode is in cell A2 in the Excel spreadsheet. The formula in cell B2 will be:

=RIGHT(A2,LEN(A2)-4)

So how does this formula work? Let’s break this down so you can understand how it works.

RIGHT Function

The RIGHT function extracts a given number of characters from the right side of a specified text. For example =RIGHT(“bananas”,4) will result in “anas”

LEN Function

The LEN function extracts the length of a given string. For example =LEN(“apples”) will result in 6 as there are 6 characters in the string “apples”.

RIGHT(A2,LEN(A2)

This section of the formula will return 8. For the first argument of the RIGHT function you have to specify what text to use. In this example it is cell A2 i.e. the postcode. For the second argument you have to specify the number of characters you want to extract. For this argument I am using the LEN function which returns the number of characters of the postcode CV36 7BL which is 8. The space between CV36 and 7BL counts as a character. The formula =RIGHT(A2,LEN(A2) translates to =RIGHT(A2,8) which returns CV36 7BL.

RIGHT(A2,LEN(A2)-4)

I want to remove the first 4 characters so therefore I include a -4 at the end of the formula. LEN(A2)-4 therefore returns 4 (8-4=4).

If I simplify this further the RIGHT function is =RIGHT(A2,4) and returns CV36.

How do you Remove the First nth Character of a String?

If you want to remove the first nth characters in a string you just change the -4 at the end of the formula to whatever number of characters you want to remove. For example, if you want to remove the first 3 characters of a string then simply change the -4 to -3. so the formula becomes =RIGHT(A2,LEN(A2)-3). If you want to remove the first 2 characters then change it to -2 so it becomes =RIGHT(A2,LEN(A2)-2) and so on.

Using the Excel MID Function
Another way to remove the first 4 characters from the postcode CV36 7BL is to use the Excel MID function. Assume again the postcode is in cell A2 and the formula is in cell B2.

The formula is now =MID(A2,5,LEN(A2))

So how does this formula work? I will explain each section of the MID formula.

The MID Function

The Excel MID function extracts the middle of a text based on the specified number of characters. For example, =MID(“bananas”,3,2) returns “na”. The first argument is the text string or a cell reference you want to extract from. The second argument is the first character you want to extract. The third argument is the number of characters you want to extract.

=MID(A2,5

This section of the formula is saying start from the fifth character of the postcode CV36 7BL. This means that it will start from the space as the space is the fifth character along from the left.

LEN(A2)

The LEN function is returning the number of characters of the postcode CV36 7BL which is 8.

=MID(A2,5,LEN(A2))

If you simplify this formula the MID function is =MID(A2,5,8). It starts from the space and extracts 8 characters along. Because there is only 3 characters after the space it therefore extracts 7BL.

How do you Remove the First nth Character of a String?

If you want to remove the first nth character then just add a 1 in the MID functions second argument. For example if I want to remove the first 3 characters then I enter 4 in the MID functions second argument so it becomes =MID(A2,4,LEN(A2)). If I want to remove the first 2 characters then just enter 3 for the second argument so it becomes =MID(A2,3,LEN(A2)).

Using the Excel REPLACE Function
Carrying on from the theme of removing the first 4 characters from the postcode CV36 7BL I will now show you how to do this using the Excel REPLACE function. Again I assume the postcode is in cell A2 and the formula is in cell B2.

The formula in cell B2 is now =REPLACE(A2,1,4,”")

I will now show you how this formula works.

The REPLACE Function

The REPLACE function replaces a set of characters in a string with another set of characters. The first argument of the replace function is the string or the cell you want to replace characters with, i.e. the postcode in cell A2. The second argument is the position of the old text to begin replacing characters. The third argument is the number of characters you want to replace the old text with. The fourth argument is the new characters you want to replace the old text with.

REPLACE(A2,1,4,”")

The first argument is the postcode in cell A2. The second argument is the start number. I want to start from the beginning so I enter 1. The third argument is 4 as I want to replace the first 4 characters with new text. The last argument is two quotation marks which mean empty strings. I want to replace the first 4 characters with empty strings so I am left with the last 3 characters.

Coming up short on information before the month’s end is a more typical issue than you may suspect, and it can indeed be a bad dream if it occurs at any rate expected time, for example, amidst summer, when we are distributing every one of our photos in interpersonal organizations. Along these lines, beneath we share a few hints you can consider to spare information on your iPhone.

Enhance the utilization of information on Facebook

The essential thing you ought to recall is that the speediest application that closures with your megas are Facebook. The reason is straightforward, because being such a well known friendly community, sends notices always, and furthermore has a significant number of media substance, for example, GIFs, photos or recordings that are played naturally, among other deciding elements.

Like this, it is prudent to control the utilization of this application, with such essential subjects as handicapping programmed playback if we are utilizing versatile information. To do this, we need to go to the ‘Settings’ of the Facebook application on our iPhone, at that point go to the ‘Record settings’ segment, and after that pick ‘Recordings and Photos.’ There we should pick ‘Programmed playback,’ and select ‘Just with WiFi associations.’

In iOS 10 we have the likelihood to survey what has been the utilization of information for every application that we have introduced on our iPhone. To do this, we need to go to ‘Settings,’ at that point go to ‘Versatile information,’ and there approve the utilization of portable information or pick interface with WiFi. Like this, you will see that there are numerous applications that you could utilize just when you have WiFi association, abstaining from spending your information.

Likewise, this area not just demonstrates to us how much information we expend for each application that we have introduced on our iPhone, yet also enables us to reset this figure each time our charging period closes, to take more control of our movement.

Another development that you can do is debilitate the information out of sight. Along these lines, you keep applications from utilizing your portable information regardless of whether you are not using them at any given time. To do this, you should go to ‘Settings,’ ‘General’ and afterward ‘Refresh out of sight.’

On the other hand, in case you are at a time when you realize that you needn’t bother with your versatile information by any means, the most fitting thing to spare is that you deactivate them. You need to go to the ‘Settings,’ and enter the segment ‘Versatile information’ so that, promptly, you disable this element.

wifi help

The ‘WiFi Assistance’ is likewise a component that you can kill to spare information. Keep in mind that this capacity is organizing the speed and nature of association, so that in the event that you achieve a point in the house where the WiFi flag was extremely frail, the iOS gadget consequently changes to the versatile system on the off chance that it is better, for Offer a superior client encounter.

At long last, there is a subject that you can control, and that is identified with the utilization of gushing application information. What they ought to do is kill ‘astounding gushing’ on Apple Music, Spotify, and Netflix. On account of the music administration of the firm of Cupertino, they should go to the ‘Settings’ of the telephone, at that point to ‘Music’ and there in the area ‘Cell information’ deactivate the ‘Transmission of high caliber.’

In Spotify, it works unexpectedly, because the alteration is produced using the application itself, in ‘Arrangement’ and the choice ‘Nature of the transmission.’ For Netflix, we need likewise to pick the low video quality.
