Name a variable with a different variable

Question

My goal is to name a new variable with the content/string of a different variable.

function foo(id) {
    var example + id; // So basically add the id to the example variable making something like example1 etc...
}

foo(1)

example1 = "text"
console.log(example1) // And it logs "text"

Hope that explains it and that you can give a good response thanks!

too lazy to look for the dupe.... Use an Object or an Array.... do not create more variables — epascarello, Jan 04 '19 at 14:50
Any time you find yourself wanting variables dynamically named "something1", "something2", "something3", and so on then what you really want is called an "array". — David, Jan 04 '19 at 14:53

You can use an associative array:

var something=[];
something["example" + 1] = "hello"

console.log(something["example1"]) => "hello"

should use an object, not an array – epascarello Jan 04 '19 at 14:50
Yes, that is one option. Beginners understand arrays more easily than objects. – Diodeus - James MacFarlane Jan 04 '19 at 14:52
I would like to here about the object way, if possible... Im not actually that beginner in web development theres just a few things i haven't either used in a while or even got to learning! – undefinedChar Jan 04 '19 at 14:53
It's almost the same code. Just replace the first line with `var something = {};`. – Magus Jan 04 '19 at 14:54
It's just that in javascript, an array is also an object. So the tend to have some behavior in common (like accepting a string in a `[]` operator). – Magus Jan 04 '19 at 14:55
"Beginners understand arrays more easily than objects." I can open a window with a hammer, it works, but it is not really the test tool for the job. – epascarello Jan 04 '19 at 14:58
