By learning and using these features, you can write cleaner, more efficient, and more readable JavaScript code. These are just a few of the many new features and improvements introduced in ES6. This can be useful when working with functions that take a variable number of arguments. Rest parameters: Rest parameters allow you to pass an arbitrary number of arguments to a function as an array. Default parameters: Default parameters allow you to specify default values for function parameters, which will be used if no value is provided when the function is called.ġ0. This allows for better organization and separation of code, and makes it easier to share code between different files and projects.ĩ.

Modules: ES6 introduced a standard syntax for creating and importing modules in JavaScript. Perhaps the greatest benefit of using arrow functions is with methods like setTimeout () and () that usually require some kind of closure, call (), apply (), or bind () to ensure that the function is executed in the proper scope. They allow you to write code that will run when an asynchronous operation is completed, rather than waiting for the operation to finish.Ĩ. Promises: Promises are a way of handling asynchronous code in JavaScript. Classes: ES6 introduced a new syntax for defining classes in JavaScript, making it easier to create and work with object-oriented code.ħ. Now newArray has the value of array and thenit own unique value 5,6Ħ.
