Lodash _.defer() Method

0 0 1 minute read

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

The _.defer() method in lodash is used to defer the calling of func parameter until the recent call stack is cleared. Moreover, any further arguments are provided to func parameter of this method when it is called.

Syntax:

_.defer(func, [args])

Parameters: This method accepts two parameters which are described below:

func: It is the function which is to be deferred.
[args]: It is the arguments with which the func is being called.

Return Value: This method returns the timer id.

Example 1:

Javascript

// Requiring lodash library 
const _ = require('lodash'); 
  
// Calling defer() method with 
// its parameter 
_.defer(function(content) { 
  console.log(content); 
}, 'zambiatek!'); 
  
// Prints content after this 
console.log('Content:');

Output:

Content:
zambiatek!

Example 2:

Javascript

// Requiring lodash library 
const _ = require('lodash'); 
  
// Defining func parameter 
let func = number => { 
  console.log(number); 
}; 
  
// Defining for loop 
for(let i = 1; i <= 5; i++) { 
      
    // Calling defer() method 
    // with its parameter 
    _.defer(func, i); 
} 
  
// Prints integer after this 
console.log('Integers are as follows:'); 

Output:

Integers are as follows:
1
2
3

5
