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)); } |
Output:
9 5 2 11 5
