Lodash _.defaultTo() Method
Lodash _.defaultTo() method is used to check the given value and determine if a default value should be restored in its place. When the value is NaN, null, or undefined, the value given in the defaultValue parameter is returned.
Syntax:
_.defaultTo( value, defaultValue );
Parameters:
- value: This parameter holds the value to check.
- defaultValue: This parameter holds the default value to be restored.
Return Value:
This method returns the resolved value.
Example 1: In this example, we are getting the same value because the given value is a valid number.
Javascript
// Requiring the lodash library const _ = require( "lodash" ); // Return the resolved value // by _.defaultTo() method console.log(_.defaultTo(5, 15)); // Return the resolved value // by _.defaultTo() method console.log(_.defaultTo(82, 43)); |
Output:
5
82
Example 2: In this example, we are getting the default value because the given value is not a valid number.
Javascript
// Requiring the lodash library const _ = require( "lodash" ); // When the value is NaN, defaultValue // is returned by _.defaultTo() method console.log(_.defaultTo( null , 15)); // When the value is undefined, defaultValue // is returned by _.defaultTo() method console.log(_.defaultTo(undefined, 43)); |
Output:
15
43
