JS Array a['1'] doesnot gives an error

Question

I have declared an array a = [1,2,3,4,5]

When I write a[1] it returns 2 which is perfectly fine but when I write a[\'1\']

Answer 1

All property names are strings.

If you pass a number, it gets converted to a string before being used to look up the property value.

console.log(1 == '1');
