In preparation to work on enabling https://www.typescriptlang.org/tsconfig/#strictNullChecks, I fixed all the issues outside of
web_srcthat came up when the option was enabled. There was also one lint issue in web_src that apparently only came up with the option enabled, so I fixed that as well.isTruthyis introduced because Typescript has a bug regardingfilter(Boolean)which they are seemingly unwilling to fix.
