A space before bracket notation is allowed in JavaScript (when setting or getting an object property). For example, the following is valid:
const prop = 'foo';
const obj = { baz: 'qux' };
obj [prop] = 'bar';
console.log(obj [prop]); // 'bar'
This is purely a stylistic preference, and is valid JavaScript syntax.
