Lodash _.union() method is used to take n number of arrays and create an array of unique values in order, from all given arrays using SameValueZero for equality comparisons.
Syntax:
_.union(*arrays);
Parameters:
- arrays: This parameter holds arrays to inspect.
Return Value:
This method is used to return the new array of combined values.
Example 1: In this example, we are passing two different arrays into the _.union() method and printing the result in the console.
Javascript
// Requiring the lodash library const _ = require( "lodash" ); // Use of _.union() method let gfg = _.union([20, 12], [8, 15, 6]); // Printing the output console.log(gfg); |
Output:
[20, 12, 8, 15, 6]
Example 2: In this example, we are passing three different arrays into the _.union() method and printing the result in the console.
Javascript
// Requiring the lodash library const _ = require( "lodash" ); // Use of _.union() method let gfg = _.union([1, 2, 3], [3, 4, 5], [6, 2, 7]); // Printing the output console.log(gfg); |
Output:
[1, 2, 3, 4, 5, 6, 7]
