`_.map` function on array using JavaScript Library underscore.js ( #shorts )

Hi Friends,

`_.map` function on array using JavaScript Library underscore.js

`_.map` is a utility function in Underscore.js library that allows you to transform each element in a collection using a specified transformation function. It provides a way to apply a common operation or transformation to each element and collect the results in a new array.

In below example, we have an array of numbers numbers. We use _.map to apply the transformation function, which multiplies each number by 2, to each element in the array. The resulting doubledNumbers array contains the transformed values [2, 4, 6, 8, 10].

Note: _.map can also be used with objects

// syntax
_.map(collection, iteratee)

// example
var numbers = [1, 2, 3, 4, 5];

var doubledNumbers = _.map(numbers, function(number) {
return number * 2;
});

console.log(doubledNumbers);
// [2, 4, 6, 8, 10]
