What exactly it denotes when a key inside a JavaScript object is in square braces

Question

  const sample=  {
                   [name]:value
                 }

What exactly the above JavaScript object represents

it means to use the variable `name` and the value it holds as the key, not `"name"` as the key. — Nick Parsons, Feb 20 '19 at 06:59
This is not JSON, but a JavaScript Object. JSON is a string based representation of data. And the square braces would not be a valid syntax in JSON. — t.niese, Feb 20 '19 at 07:00

This means name is variable

like

let name = 'John';

 const sample=  {
                   [name]:value
                 }

So sample will be like this

sample.John = value

Try this

let name = 'John';

 const sample=  {
                   [name]:"I am John"
                 }
                 
console.log(sample);
