0 0 1 minute read

The Lodash _.isFinite() Method checks whether the given value is a primitive finite number or not and returns the corresponding boolean value.

Syntax:

_.isFinite( value )

Parameters: This method accepts single parameter as mentioned above and described below:

value: This parameter holds the value that to be checked for a primitive finite number.

Return Value: This method returns a Boolean value(Returns true if the given value is finite number, else false).

Example 1:

Javascript

// Defining Lodash variable  
const _ = require('lodash');  
  
// Checking for Finite Value  
console.log("The Value is Finite : "
        +_.isFinite(10));

Output:

The Value is Finite : true

Example 2: For Infinity, it returns false.

Javascript

// Defining Lodash variable  
const _ = require('lodash');  
  
// Checking for Finite Value  
console.log("The Value is Finite : "
        +_.isFinite(Infinity));

Output:

The Value is Finite : false

Example 3: For strings, it returns false.

Javascript

// Defining Lodash variable  
const _ = require('lodash');  
  
// Checking for Finite Value  
console.log("The Value is Finite : "
        + _.isFinite("gfg"));

Output:

The Value is Finite : false

Example 4:

Javascript

// Defining Lodash variable  
const _ = require('lodash');  
  
// Checking for Finite Value  
console.log("The Value is Finite : "
    +_.isFinite(Number.MAX_VALUE));
