The return value from the `typeof` operator is always one of six (seven as of ES6!) string values. That is, `typeof "abc"` returns `"string"`, not `string`.
The return value from the `typeof` operator is always one of six (seven as of ES6! - the "symbol" type) string values. That is, `typeof "abc"` returns `"string"`, not `string`.
Notice how in this snippet the `a` variable holds every different type of value, and that despite appearances, `typeof a` is not asking for the "type of `a`", but rather for the "type of the value currently in `a`." Only values have types in JavaScript; variables are just simple containers for those values.
