Lodash _.dec() Method

0 0 1 minute read

The Lodash _.dec() method returns the result by decrementing the given value by 1.

Syntax:

_.dec( value );

Parameters: This method takes a value and decrements them.

Return Value: This method returns the result by decrementing the given value by 1.

Note: This will not work in normal JavaScript because it requires the lodash.js contrib library to be installed. Lodash.js contrib library can be installed using npm install lodash-contrib –save.

Example 1:

Javascript

// Defining lodash contrib variable  
var _ = require('lodash-contrib');  
  
var val = 33  
var decrVal  = _.dec( val );  
    
console.log("The Given value is :", val);  
console.log("The Decrement of Given value is :", decrVal);

Output:

The Given value is : 33
The Decrement of Given value is : 32

Example 2:

Javascript

// Defining lodash contrib variable  
var _ = require('lodash-contrib');  
  
var val = 100  
var decrVal  = _.dec( val );  
    
console.log("The Given value is :", val);  
console.log("The Decrement of Given value is :", decrVal);

Output:

The Given value is : 100
The Decrement of Given value is : 99
