Unexpected template string when Creating Object

Question

I create a Object like below,

var s = {
  `1234`:`string`
}

But, It will throw the below Error,

Uncaught SyntaxError: Unexpected template string

How Can I create Such Elements?

Object declaration in javascript is done using single or double quotes and not backquotes `var s = { "1234": "string" }` — Ankit Agarwal, Sep 26 '18 at 09:09

You could use computed property names with brackets, because the template literal returns a string, which works like a variable.

var object = { [`1234`]:`string` };

console.log(object);

With that we can also avoid the backquote in `1234`. Simply `[1234]` – Ankit Agarwal Sep 26 '18 at 09:13

i think it's more how to use a template litral as key (with computed values), not just taking a constant as key. but i might be wrong ... – Nina Scholz Sep 26 '18 at 09:15

You should be using quotes instead of backticks, try this:

 var s  = { '123': 'string'}
