How do I convert a string into a property in javascript

Question

Now I am sending length as a string as a function parameter.

function sample(operation){
var str="hello";
console.log(str.operation);
}

sample("length");

I am not allowed to change the way I am sending length(has to be a string).What can I do for this function to give me the expected output?

What is your expected output? Please be more specific – Cyrille Pontvieux Oct 15 '21 at 14:03 — Cyrille Pontvieux, Oct 15 '21 at 14:03

If you just want to access the property, use bracket notation for your property accessor:

console.log(str[operation])
