log("what?");

Result => what?

i don't understand well this code...

Answer 1

console.log added to object
In every calling of object log function gets data and printing it!

Answer 2

let {log} = console;

is equivalent to

let log = console.log;

This technique is called object destructuring.

const {log: LOG= alert} = console; //
LOG('OUTPUT'); // will consoled if there is a log method in console object if it is not will use the alert replace it log: LOG is the function name in constant
