Javascript doubt

Question

Because this code has output: 10
let{log} = console;
log("10");

Answer 1

Brayan Pinilla look that code like this:
let log = console.log;
log("10");

Mira el código así:
let log = console.log;
log("10");
let {log} = console Primero verifica si console tiene una propiedad log(un método en este caso) y luego asigna esa propiedad a una variable let log.

Answer 2

Destructuring assignment is a ES6 syntax.

console.log is the log method on the console object.

With { } in assignment, it detaches the method from console object.

You can even rename the method in object destructuring, like this:
