Javascript – How to make a variable addressable by name as string in JavaScript


Is there a way to convert variable names to strings in javascript? To be more specific:

var a = 1, b = 2, c = 'hello';
var array = [a, b, c];

Now at some point as I go through the array, I need to get variable names (instead of their values) as strings – that would be 'a' or 'b' or 'c'. And I really need it to be a string so it is writeable. How can I do that?

Best Solution

Use a Javascript object literal:

var obj = {
    a: 1,
    b: 2,
    c: 'hello'

You can then traverse it like this:

for (var key in obj){
    console.log(key, obj[key]);

And access properties on the object like this:

console.log(obj.a, obj.c);
