Math.max() not working as expected

Question

I have this following function, where Math.max() is not working as expected. It is always alerting the 1st value from the arguments that are passing. Where is the mistake?

function large(arr) {
   alert(Math.max(arr))
}

large(1,2,3,4,5);

Answer 1

You are passing multiple arguments, but your function only uses the first one.

In ES5 and before, you can use the apply method of a function and the arguments object:

function large() { 
   alert(Math.max.apply(Math, arguments)) 
} 

large(1,2,3,4,5);

In ES6 you can use the rest and spread operator:

function large(...arr) { 
   alert(Math.max(...arr)) 
} 

large(1,2,3,4,5);

Answer 2

You can do like this.

If you want to use the arguments you can avoid the parameter of the function. Then use the apply function to call Math.max

function large() {
var _max = Math.max.apply(Math, arguments);
alert(_max)
};
large(1, 2, 3, 4, 5, 20,9000);
