I was testing something in my Chrome dev tools with the following code:

const one = {a: "a", b: "b"};
const two = { ...one, c: "c" };
VM417:1 Uncaught SyntaxError: Unexpected token ...

Why do I get this error on the spread operator?

You are attempting Object rest/spread, which has not quite made it into the ES6 specification. So, spreading into an object isn't supported yet, only spreading into an array.

Object rest/spread is currently a Stage 3 proposal.

Now spreading the Object is supported in ES6 const one = {a: "a", b: "b"}; const two = { ...one, c: "c" };
