Print / display a JavaScript variable's name instead of it's value

Question

Is it possible to print / display a JavaScript variable\'s name? For example:

var foo=5;
var bar=6;
var foobar=foo+bar;

document.write(foo+ \"
\");         


        

Answer 1

Another possible solution can be "Object.keys(this)".... This will give you all the variable names in an array.
