javascript-lodashHow can I use Lodash to union two JavaScript arrays?

Using Lodash's union method, two JavaScript arrays can be combined into one. This method will remove duplicate values from the two arrays and return a new array with all unique values from both.

Example code

const arr1 = [1, 2, 3];
const arr2 = [2, 3, 4];

const unionArr = _.union(arr1, arr2);

console.log(unionArr);

Output example

[1, 2, 3, 4]

The code above uses Lodash's union method to combine two arrays, arr1 and arr2. The method returns a new array, unionArr, which contains all unique values from both arr1 and arr2.

Code explanation

• _.union: This is the Lodash method used to combine two arrays.
• arr1 and arr2: These are the two arrays being combined.
• unionArr: This is the new array which contains all unique values from both arr1 and arr2.
