What is console.log?

Question

What is the use of console.log?

Please explain how to use it in JavaScript, with a code example.

Answer 1

You use it to debug JavaScript code with either Firebug for Firefox, or JavaScript console in WebKit browsers.

var variable;

console.log(variable);

It will display the contents of the variable, even if it is a array or object.

It is similar to print_r($var); for PHP.
