Lodash _.noop() method is used to return “undefined” irrespective of the arguments passed to it.
Syntax:
_.noop();
Parameters:
This method can take optional parameters of any type.
Return value:
This method returns undefined.
Example 1: In this example, we are storing the undefined value in a variable by the use of the _.noop() method and comparing it to another variable having an undefined value and checking whether both are equal or not.
Javascript
// Requiring the lodash library const _ = require("lodash");// Use of _.noop() method let val1 = undefined;let val2 = _.noop();if (val1 == val2) console.log("val1 and val2 are equal");else console.log(`val1 and val2 are not equal`); |
Output:
val1 and val2 are equal
Example 2: In this example, we are creating an array and an object by the use of the _.noop() method and printing their values in the console.
Javascript
// Requiring the lodash library const _ = require("lodash");// Use of _.noop() method let obj = new Object(_.noop())console.log(`Object is ${obj.Object}`)// Use of _.noop() method let arr = new Array(_.noop())console.log(`Array is ${arr[0]}`) |
Output:
Object is undefined
Array is undefined
