• Change the variable name to myValidator to avoid a duplicate conflict - Modules Section.
• Typo fix for a module import using import =.

I would change it to:

let obj = {
   [sym]: "value"
};

console.log(obj[sym]); // "value"

[DanielRosenwasser]

I had the same idea actually, good call.

Only thing is that we never explained computer properties 😄

@mhegazy made me realize that if noImplicitAny is set to false then the code works fine. I've set it in my tsconfig file. This kind of mistake won't happen again. Sorry.

Actually, we try to have the handbook examples clean for "noImplicitAny": true. Can you re-add the any assertions in Advanced Types.md?

[sandersn]

After you add the casts back in, 👍

[mhegazy]

👍

Then, I will reopen issue #239, because the code doesn't work unless noImplicitAny is false.
