console.log.apply is equivalent to
console.log.
to print an array, it should look like this:
console.log.apply (console.log, [[12fourth answer]])
console.log() //
fn.apply(thisArg, [argsArray]) // this, fnargsArray
12 34 5
console.log(12,34,5) do you understand?
my understanding is that when a function calls fn.apply (context, ArrayLikeObj) is equivalent to fn (.ArrayLikeObj)
generally speaking, I will check the document first

console.log.apply (console.log, [12734 console.log.apply 5]) is equivalent to
