Tuple issues

Bug Report

First time to report issues on typescript...
I am working with Tuple.
The Tuple variable could not directly access the index that larger than its length.
It will show up an error, but it push any types of variable as I want and can access them by for loop.

type A =[number,number,number,string];
const a :A = [1,2,3,'1'];

a.push("123")
a.push("123")

console.log(a.filter((i)=>i===4))

It did not show up any error.
