1This is possible, yes. Can you add any attempts at solving the problem on your own? – Luca Kiebel Feb 12 '19 at 19:20

Yes, It is possible to create a variables using user-defined name. take this example.
var var_name = 'test_var';
const n = 120;
this[var_name] = n;
alert("printing using this[var_name]: "+this[var_name]);
alert("printing using test_var: "+test_var);<!DOCTYPE html>

You can define an object with all your user-defined variables.
const VAR_NAME = 'myVar'
const VAR_VALUE = 'myValue'
var obj = {
[VAR_NAME]: VAR_VALUE
}
console.log(obj)
console.log(obj[VAR_NAME])
