Turn integers (NOT string) separated by comma into array JS

Question

it seems a pretty easy question but I can't find a solution. I need to turn the argument of this function (just numbers followed by a comma) into an array full of numbers. The problem is, the argument is not a string and I cannot add the "" to it. If I console.log([card]) only the first number appears into the array (the 2)... I tried to do a loop but it didn't work out. Thanks for the help!

function cc(card) {

}
cc(2,3,4,5,6);

You are not sending one single argument. When you do cc(2,3,4,5,6); you are sending 5 different argument. You are seeing only the first argument because JS is very perimissible and won't complain if you send a different amount of argument that what it is suposed to receive — ffigari

Ok I understand... so is there a way to use all the numbers in that "list"? — mike87

Does your function needs to be able to receive any amount of parameters? — ffigari

about five of them, as in the example. However, if there isn't a way of addressing all numbers simply because I am not allowing the function to call them, it might be simply a problem of poor description of the exercise I am doing. Thanks for your help mate — mike87

Anyway, just in case, you can use the arguments variable:

var cc = function () { console.log(arguments) }

cc(1,2,3,4,5) prints Arguments { 0: 1, 1: 2, 2: 3, 3: 4, 4: 5, … } and cc(2,3,4,5,6,7,8) prints Arguments { 0: 1, 1: 2, 2: 3, … }

and just to add one more thing I just discovered, to end up with an array filled with the arguments, you can also do Object.values(arguments) , using the method Object.values() plus the above mentioned arguments . Very good stuff indeed!
