[chore] sanitize.js | Useless assignment to local variable

[BeauBouchard]

at lib/utils/sanitize.js:35

The value assigned to l here is unused. A value is assigned to a variable or property, but either that location is never read later on, or its value is always overwritten before being read. This means that the original assignment has no effect, and could indicate a logic error or incomplete code.
