0 0 1 minute read

The _.random() method is used to return a random number which is in the range provided to the function. If floating is true, or either lower or upper are floats, a floating-point number is returned instead of an integer.

Syntax:

_.random([lower = 0], [upper = 1], [floating])

Parameters: This method accepts three parameters as mentioned above and described below:

lower: This parameter holds the lower bound.
upper: This parameter holds the upper bound.
floating: This parameter specifies returning a floating-point number.

Return Value: This method returns the random number.

Example 1:

Javascript

// Requiring the lodash library   
const _ = require("lodash");   
          
// Use of _.random method  
console.log(_.random(10));  
console.log(_.random(10, 12));  
console.log(_.random(10, 12));  
console.log(_.random(10.3, 12.5));  

Output:

3
11
10
12.000118273018167

Example 2:

Javascript

// Requiring the lodash library   
const _ = require("lodash");   
  
// lower and upper value 
let lower = 2;  
let upper = 11;  
    
// Printing 5 random values  
// in range 2 and 11  
for (let i = 0; i < 5; i++) {  
    console.log(_.random(lower, upper));  
}
