Why JavaScript has following kind of wired behaviour?

Question

I was trying something in the browser console and I encountered the following scenario. What is happening under the hood here?

'hello'[4] === 'hello'[1,2,3,4] === true;

`'hello'[4]` gives `o` as does `'hello'[1,2,3,4]`. Why `'hello'[1,2,3,4]` returns 'o' though is probably your real question — phuzi, Nov 06 '19 at 11:07

Because both 'hello'[4] and 'hello'[1,2,3,4] returns o

why does `'hello'[1,2,3,4]` return `o` though? – Ayush Gupta Nov 06 '19 at 11:08
It takes the last index value `4` and becomes similar to `'hello'[4]`. Hence, `'hello'[1,2]` returns `l` – Michael 'Maik' Ardan Nov 06 '19 at 11:09
