Javascript `Math.max()` is used to find the largest or max number among a series of numbers. `max()` accepts variable number of arguments.
This means that you can pass any number of arguments to `max()`.
As per official MDN docs,

The `Math.max()` function returns the largest of the zero or more numbers given as input parameters.

Syntax
Syntax of `max()` function is

max(num1, num2, num3, …..)

`max()` is a static function and belongs to javascript `Math` object and that is why it is invoked as `Math.max()`.
max() return values
`max()` returns different value as per the arguments passed to it.
1. Maximum value when more than one numbers are passed.
2. `NaN` when an argument cannot be converted to a number such as a string.
3. `-Infinity` when no arguments are passed.
max() examples
Following are some of the usage examples of `max()` with different input arguments.

```let max = Math.max(12,56,9,0,35);
console.log('Max with all positive numbers: ' + max);

max = Math.max(-12,-56,-9,-1,-35);
console.log('Max with all negative numbers: ' + max);

max = Math.max(12,56,9,0,'a');
console.log('Max with one invalid argument: ' + max);

max = Math.max();
console.log('Max with no arguments: ' + max);```

This prints

Max with all positive numbers: 56
Max with all negative numbers: -1
Max with one invalid argument: NaN
Max with no arguments: -Infinity

In case of negative numbers, `max()` returns the number having smallest numeric value.

max() with arrays
`Math.max()` can be used to find maximum element of a javascript array. But you cannot directly pass an array as argument to `max()` as it will return `NaN`.
For using array with `max()`, you need to destructure it using javascript spread operator, which extracts individual elements from the array.
spread operator is used by placing three dots() before the array
Example,

```const arr = [12,56,9,0,35]
let max = Math.max(...arr);
console.log('Max with an array: ' + max);```

which prints

Max with an array: 56

As with numbers, if the array contains an element that cannot be converted to a number, then the result is `NaN`.
Also, if the array is empty, the `max()` will return `-Infinity`.
