The Lodash _.isNumeric() method checks whether the given value is a Numeric value or not and returns the corresponding boolean value. It can be a string containing a numeric value, exponential notation or a Number object, etc.
Syntax:
_.isNumeric( value );
Parameters: This method takes single parameter as mentioned above and described below:
- value: Given value to be checked for Numeric value.
Return Value: This method returns a Boolean value true if the given value is Numeric, else false.
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.
Example 1:
Javascript
var _ = require( 'lodash-contrib' );
console.log( "The Value is Numeric : " + _.isNumeric(10000));
console.log( "The Value is Numeric : " + _.isNumeric(10.5));
console.log( "The Value is Numeric : " + _.isNumeric( 'G' ));
console.log( "The Value is Numeric : " + _.isNumeric( 'Geeks' ));
|
Output:
The Value is Numeric : true
The Value is Numeric : true
The Value is Numeric : false
The Value is Numeric : false
Example 2:
Javascript
var _ = require( 'lodash-contrib' );
console.log( "The Value is Numeric : " + _.isNumeric([1,10]));
console.log( "The Value is Numeric : " + _.isNumeric( "500" ));
console.log( "The Value is Numeric : " + _.isNumeric({}));
console.log( "The Value is Numeric : " + _.isNumeric( null ));
