Spread syntax doesn't work for strings for arrays

[highlou]

Hi I was working on some project and had an issue with the spread operator on strings.

How to replicate:

• Go to JSFiddle
• Select TypeScript
• Remove the default code in the TypeScript panel
• Paste this TypeScript code

let chars = [...'hello'];
console.log(chars);

• Click Run

After clicking run, it shows in the console (on my end):

"[Line 15] Uncaught TypeError: Cannot use 'in' operator to search for '0' in hello"

Here's a screenshot:

Here's also the link to the JSFIddle.

I'm using .split('') in the meantime.
