Why does this simple Math.max() example return NaN?

Question

var a = [875, 551];
console.log( Math.max(a) ); // NaN

You may think you can pass an array because of the syntax:

Math.max([value1[, value2[, ...]]])

The brackets in this syntax indicate that the value is optional, not that it is a member of an array.

Ok thank you, the issue was really just my ability to read documentation. – somebodysomewhere May 14 '18 at 18:30

 Math.max(...a)

You need to spread it.
