javascript-lodashHow do I use _lodash to replace elements in a JavaScript array?


Using _lodash, you can easily replace elements in a JavaScript array. Here's an example:

const _ = require('lodash');

let array = [1, 2, 3, 4, 5];

let replaced = _.replace(array, 3, 7);

console.log(replaced);
// Output: [1, 2, 7, 4, 5]

The code above uses the _.replace() method from _lodash to replace the element 3 in the array array with the element 7. This results in a new array being returned with the element 3 replaced by 7.

The code can be broken down into the following parts:

  1. The first line imports the _lodash library.
  2. The second line creates an array with the elements 1, 2, 3, 4 and 5.
  3. The third line uses the _.replace() method to replace the element 3 in the array array with the element 7.
  4. The fourth line logs the new array to the console.

For more information on the _.replace() method, please refer to the _lodash documentation.
