Too Many Arguments in JavaScript
How many are too many?
In the short example below, JavaScript engine is complaining about too many arguments to Math.max().
> const longArray = Array(10000000);
undefined
> longArray.fill(0);

> Math.max(...longArray)
Uncaught RangeError: Maximum call stack size exceededIt seems there is an upper limit for the number of arguments you can pass to a function.
The consequences of applying a function with too many arguments (that is, more than tens of thousands of arguments) varies across engines. (The JavaScriptCore engine has hard-coded argument limit of 65536.
Here is a safe way to calculate the maximum value in an array.
const max = arr.reduce((max, v) => Math.max(max, v), 0);Reference
Function.prototype.apply() - JavaScript | MDN
The apply() method calls a function with a given this value, and arguments provided as an array (or an array-like object).
