TypeScript Bazel Lint Rule Functions Must Return Value

ts-bazel-lint-rule-func-must-return-value.ts

// A list of well-known functions that the return value must be used. If unused
// then the function call is either a no-op (e.g. 'foo.trim()' foo is unchanged)
// or can be replaced by another (Array.map() should be replaced with a loop or
// Array.forEach() if the return value is unused).
