Example
Following is the code −
function callBackFunctionDemo({ cl: { callFunctionName = "callBackFunction", values = 100 } = {} } = {}) { console.log(callFunctionName); console.log(values); } //This will print the default value. // 100 callBackFunctionDemo(); //This will print the given value. //500 callBackFunctionDemo({ cl: { values: 500 } });

node fileName.js.
Here, my file name is demo296.js.

This will produce the following output on console −
PS C:\Users\Amit\javascript-code> node demo296.js callBackFunction 100 callBackFunction 500
