Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.
The _.negate() method used to create a function that negates the result of the given predicate function.
Syntax:
_.negate( predicate )
Parameters: This method accepts a single parameter as mentioned above and described below:
- predicate: This parameter holds the predicate function to negate.
Return Value: This method returns the new negated function.
Example 1:
Javascript
// Requiring the lodash library  const _ = require("lodash");    // Function to check the number // is divisible by 5 or not function number(n) {   return n % 5 == 0; }    // Using the _.negate() method  console.log(   _.filter([4, 6, 10, 15, 18],   _.negate(number)) ); |
Output:
[4, 6, 18]
Example 2: Â
Javascript
// Requiring the lodash library  const _ = require("lodash");    // Function to check the // number is odd or not function isOdd(n) {   return n % 2 != 0; }    // Using the _.negate() method  console.log(   _.filter([2, 4, 7, 12, 16, 19],   _.negate(isOdd)) ); |
