Add braces to the fast-path if statement.
Change line 26 to use a block. This keeps the optimization unchanged and complies with the rule: “Always use curly braces for if, else, loops, and similar control statements.”
Proposed fix
- if (path.indexOf('//') === -1) return path+ if (path.indexOf('//') === -1) {+ return path+ }As per coding guidelines, TypeScript control statements must always use curly braces.

Summary
Split out of #8085 so bundle size and performance can be measured independently.
cleanPathruns onjoinPaths/resolvePathfor every navigation. Most paths never contain//, so the/{2,}regex is wasted work.Return the input as-is when
indexOf('//')misses. Same result when it hits.Test plan
