What is the use of the Map Function in JavaScript ?

The map function is used to transform elements in an array. It is a higher-order function that takes a callback function as an argument and applies that function to each element of the array, creating a new array with the results. The primary goal map is to perform a specific operation on each element of an array and generate a new array based on those transformations.

• Transformation: The primary purpose of map is to transform each element of an array. The transformation logic is defined by the callback function provided as an argument to map. This function is applied to each element, and the results are collected into a new array.
• Creating a New Array: Unlike some array methods that modify the original array, map does not alter the original array. Instead, it returns a new array containing the results of applying the provided callback function to each element of the original array.
• Simplified Syntax: The syntax map is concise and expressive. It enhances code readability by encapsulating the transformation logic in a single line, promoting a functional programming paradigm.
