The _.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 underscore.js contrib library to be installed. Underscore.js contrib library can be installed using npm install underscore-contrib –save.
Example 1:
Javascript
// Defining underscore contrib variable var _ = require('underscore-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 underscore contrib variable var _ = require('underscore-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
