The _.repeat() method takes an integer and a value and creates an array of that size containing the given the value given integer times.
Syntax:
_.repeat(n, value)
Parameters:
- n: The given integer for the times the value will be in the array.
- value: The value to be in the array n times.
Return Value: This method returns a newly created array.
Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed. Underscore.js contrib library can be installed using npm install underscore-contrib –save.
Example 1: In this example, we will generate a repeat array using this method.
Javascript
// Defining underscore contrib variable var _ = require('underscore-contrib'); // Integer var integer = 10; // Value var value = "neveropen"; // Generating Array using Repeat method var arr =_.repeat(integer, value); console.log("Integer : ", integer); console.log("Value : ", value); console.log("Generated Array : ", arr); |
Output:
Integer : 10 Value : neveropen Generated Array : [ 'neveropen', 'neveropen', 'neveropen', 'neveropen', 'neveropen', 'neveropen', 'neveropen', 'neveropen', 'neveropen', 'neveropen' ]
Example 2: Value can also be an integer.
Javascript
// Defining underscore contrib variable var _ = require('underscore-contrib'); // Integer var integer = 10; // Value var value = 1; // Generating Array using Repeat method var arr =_.repeat(integer, value); console.log("Integer : ", integer); console.log("Value : ", value); console.log("Generated Array : ", arr); |
Output:
Integer : 10 Value : 1 Generated Array : [ 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 ]
