"object-maps"

This reverts commit bfe5b4c9.

This fixes #69657

This new call works as a type guard and can help avoid writing double negations

Avoid either call in cases where we were iterating over the possibly undefined value. Use `|| []` for these

Using an overload makes the code more complex and prevents  patterns such as `.then(coalesce)` or `.map(coalesce)`. It also makes it clear which code paths are actually being most used in our code

We compile using the alwaysStrict flag so these directives are not needed

This part removes most `use strict` directives that are right after the file header

fuzzyScore - allow passing of lower-case variants of things, allow passing of start positions, move whitespace starts to completion model
