Map function in JavaScript #shorts

The map() function in JavaScript is a higher-order function that allows you to iterate over an array and apply a function to each element. It creates a new array populated with the results of calling the function on every element in the original array.

The map() function takes two arguments:

* A callback function: This function is called on each element of the array. It takes three parameters: the current element, the index of the current element, and the original array.
* An optional thisArg value: This value is passed to the callback function as its this value.

The map() function returns a new array containing the results of calling the callback function on each element of the original array.

The map() function is a very powerful tool for manipulating arrays in JavaScript. It can be used to perform a variety of tasks, such as:

* Converting elements of an array
* Filtering elements of an array
* Sorting elements of an array
* Creating new arrays from existing arrays

The map() function is a very versatile function that can be used for a variety of tasks. It is one of the most commonly used array methods in JavaScript.
