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]
