The Lodash _.cloneDeepWith() method is used to clone value in a recursive way, just the same as the _.cloneWith() method but performs in a recursive manner.
Syntax:
_.cloneDeepWith( value, customizer )
Parameter: This method accepts two parameters as mentioned above and described below:
- value: This parameter holds the value which will be cloned in a recursive way.
- customizer: This parameter holds the function to customize the clone.
Return value: This method returns the cloned value.
Below example illustrate the Lodash _.cloneDeepWith() Method:
Example 1: Cloning Head element.
Javascript
<!DOCTYPE html> <html> <head> <script src= </script></head> <body> <script type="text/javascript"> function customizer(value) { if (_.isElement(value)) { return value.cloneNode(true); } } var gfg = _.cloneDeepWith(document.head, customizer); console.log(gfg === document.head); console.log(gfg.nodeName); console.log(gfg.childNodes.length); console.log(gfg); </script> </body> </html> |
Output:
Example 2: Cloning body element.
Javascript
<!DOCTYPE html> <html> <head> <script src= </script></head> <body> <script type="text/javascript"> function customizer(value) { if (_.isElement(value)) { return value.cloneNode(true); } } var gfg = _.cloneDeepWith(document.body, customizer); console.log(gfg === document.body); console.log(gfg.nodeName); console.log(gfg.childNodes.length); console.log(gfg); </script> </body> </html> |
