docs(renderer): consistent return (#382)

Line 102 - removed the block wrapper to fix an "Unexpected block statement surrounding arrow body; move the returned value immediately after the `=>`" error.
Line 102 - removed reference to index to fix the "'index' is already declared in the upper scope" and "'index' is defined but never used" errors.
