Lodash _.stubFalse() Method

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.stubFalse() method is used to always return a false value. The basic difference between using a normal false value and using the _.stubFalse() method is that lambda functions create a new different function every time they are run, so when used in React render functions, they can create unnecessary re-renders. Lodash stubs do not have this issue.

Syntax:

_.stubFalse()

Parameters: This method does not accept any parameters.

Return Value: It returns the false boolean value.

Example 1:

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Using the _.stubFalse() method
let false_val = _.stubFalse();

// Printing the output
console.log(false_val);

Output:

'false'

Example 2:

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Using the _.stubFalse() method
// to create 5 false values
let false_vals = _.times(5, _.stubFalse);

// Printing the output
console.log(false_vals);

Output:

[false, false, false, false, false]
