in JavaScript toString method doesn't directly run an empty object, instead runs on a variable which is assigned to an empty object

I tried this today on my browser console and saw something weird. Please help. Can someone help me understand why It happens ?

Try 1:

{}.toString(); // It shows an error - Uncaught SyntaxError: Unexpected token '.'

Try 2:

const a = {};
a.toString(); // It returns '[object Object]'

surround with `()`...`({}).toString()` – depperm Apr 01 '22 at 18:22
Thanks! Why It behaves like this, can you please explain ? – Sibashrit Pattnaik Apr 01 '22 at 18:23

TLDR; When a statement starts with `{` it's treated as the start of a block, not an object literal. – Barmar Apr 01 '22 at 18:45
