What is "no-string-literal" rule in tslint?

Question

The description found here is very short:

Disallows object access via string literals.

Is there any further documentation or example?

Answer 1

It means you can't access objects using the bracket notation. For example:

object["property"]

This way, a simple typo will throw an error and that's why it should be avoided. Instead, it is encouraged to use strongly-typed access.
