After that it failed with: Opera 12.17: The last successful test was 4194303 arguments. Announcing the Stacks Editor Beta release! A real-world example: The Google Closure Library defined the following function. All the power of JavaScript destructuring can be applied to parameters. Dummies helps everyone be more knowledgeable and confident in applying what they know. This code demonstrates the use of the Arguments object to present a welcome message to someone with two middle names as well as someone with one middle name. Is there a PRNG that visits every number exactly once, in a non-trivial bitspace, without repetition, without large memory usage, before it cycles? The values passed to the function will become the values of the local variables inside of the function and will be given the names of the functions parameters. Another difficulty is that each function scope defines it's own arguments object. ","authors":[{"authorId":9070,"name":"Chris Minnick","slug":"chris-minnick","description":"

If you find you need a lot of parameters, you should think about whether theres a better way to do it. There are many different factors that may limit the maximum number, and different methods for calling it may yield different results. After that it failed with: The List type is used to explain the evaluation of argument lists (see 11.2.4) in new expressions, in function calls, and in other algorithms where a simple list of values is needed.These sequences may be of any length. But I'm wondering if there is actually a limit to how many "any" can be? For this reason, its still best to use the more compatible method of setting defaults. Let's use the rest parameters to sum the arguments: numbers is a rest parameter that holds the arguments in an array [5, 6]. Let's define functions that have 0, 1 and 2 parameters: The 3 functions above were called with the same number of arguments as the number of parameters. This one is particularly interesting because Chrome itself seems to be confused about how many arguments are actually allowed.
