Question

I have a space separated string that I want to make into an array. I am using the .split(' ') method to do this. Will the resulting array have those spaces in it? For example if my string is "joe walked down the street" and I performed the method on it would the array look like this ["joe", "walked", "down", "the", "street"] or will it look like this ["joe ", "walked ", "down ", "the ", "street "]?

Answer 1

Nope, it would not have the spaces in there. It would look like this:

["joe", "walked", "down", "the", "street"]

Since spaces are a bit hard to see, let’s take a more visible example with the same effect:

var str = "joe...walked...down...the...street";
var arr = str.split("...");
alert(arr); //["joe", "walked", "down", "the", "street"]

You can test it here.
