Arrow functions were introduced in ES6 Javascript. We use Arrow functions to write shorter function syntax (For ex. let myFunction = (a, b) => a * b;).Arrow functions have a simple (concise) or the usual block body. Only a single expression is specified in a concise body, which becomes the implicit return value. You must use a return statement in a block body. 

You can remove the return keyword and the brackets if the function has only one statement and the statement returns a value. An arrow function expression is a compact traditional function expression with some differences and limitations in usage:  

  • In Arrow functions, this, arguments, or super, should not be used as methods. 
  • Arrow functions cannot be used as constructors. 
  • Arrow functions cannot be created as generator functions. 
  • Argument keywords can access the passed arguments in regular JavaScript functions when the function is invoked. But, the arrow function uses the arguments from the outer function. It does not have its arguments, and it. 
  • A keyword is needed. (that is, let, var, const) 
  • It is not suited for the call, apply, and bind methods, which all require setting a scope. 
  • A new keyword is not used to create a new object. 

Here is an example of how to do ES6 Arrow Functions:

Follow the steps carefully to get the output easily.

  1. Download and Install VS Code on your Computer.
  2. Open the VS Code and install Javascript ES6 Code Snippet and Code Runner from Extensions.
  3. Open the new file and save it as example.js (functions.js)
  4. Copy the code using the "Copy" button above, and paste it into your Javascript file. ( Remove textValue as in the preview)
  5. Run the code using (ctr+alt+N) Run button.

I hope you found this useful. I have added version information in the following sections.

I found this code snippet by searching for ' arrow function es6' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in VS Code 1.73.1 version.
  2. JavaScript (ES6) code snippets v1.8.0
  3. Code Runner v0.12.0

Using this solution, we are able to do the arrow function es6 with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to do the arrow function es6.
