const args = ['p0', 'p1', 'p2'];
call_me.apply(this, args);
See MDN docs for Function.prototype.apply().
If the environment supports ECMAScript 6, you can use a spread argument instead:
call_me(...args);

Why don't you pass the entire array and process it as needed inside the function?
var x = [ 'p0', 'p1', 'p2' ];
call_me(x);
function call_me(params) {
for (i=0; i<params.length; i++) {
alert(params[i])
}
}

Function with array as parameter - JavaScript - The freeCodeCamp Forum
March 11, 2024 - Hi everyone, I am trying to write a function which takes an array and returns a new array with the number of characters in each string from the original array, but it is not working. Only the number of characters of the first string is returned. I am almost sure that this is because the parameter suggests that there is only parameter, rather than an array of parameters, but I am not sure how this should be represented as this is how the original problem was set up and presented to me.
how do you pass an array as a parameter in a function?
Michael, I think my solution works better than testing for 'string', 'undefined' and 'number', because in JavaScript there are other types as well, such as boolean, function and object. What's even trickier is that if you use typeof with an array you don't get 'array' as the result; you get ... More on teamtreehouse.com

February 23, 2014Writing a function that takes an array as an argument and sums up all the elements
So close! It's numbers.length not length.numbers And I wouldn't declare y globally. It can be declared just above the for loop. That makes it a pure function . More on reddit.com

The spread operator is used in places where zero or more arguments are expected. It can be used with iterators that expand in a place where there may not be a fixed number of expected arguments (like function parameters).

JavaScript function definitions do not specify data types for parameters. JavaScript functions do not perform type checking on the arguments. JavaScript functions do not check the number of arguments received. Accessing a function with an incorrect parameter can return an incorrect answer:

April 15, 2022 - Similar to C/C++/Java, we can pass the entire array as a parameter to a function in JavaScript. This method of array passing is called call by reference in JavaScript. To pass an array argument to a function, simply pass the name of an array (a reference to an array) without brackets.

r/learnjavascript on Reddit: Writing a function that takes an array as an argument and sums up all the elements
July 13, 2022 -
Hi guys I am trying to write a function that takes as an argument an array and then iterates over each element and adds them together but i am having problems, id honestly really appreciate any pointers in the right direction!
this is what I have written so far;
1) Declared y as a global binding.
2) Function takes an array as an argument- (i dont know if "(...argument)" is how you do it).
3)A loop iterates over each element of the array the range of which is 0 - length of array and increments by +1.
4)Each number that is iterated is added to y.
5) y is returned
let y = 0;
function max(...numbers){
for(let x = 0; x < length.numbers; x++){
y += x;
}
return y;
}
console.log(max([1, 2, 3]));Medium

October 5, 2018 - When you define a function using a rest parameter, the arguments of the function, no matter how many they are, will be turned into an array. the spread operator allows an iterable, like an array, to be expanded in place.

Passing arrays to functions is no different from passing any other type:
var string = buildString([desc(visits), source]);
However, your function is not necessary, since Javascript has a built-in function for concatenating array elements with a delimiter:
var string = someArray.join(',');

You're over complicating things — JavaScript arrays have a built-in join method:
[ desc( visits ), source ].join( ',' );
EDIT: simpler still: the toString method:
[ desc( visits ), source ].toString();
