Rename one lexical binding and its references after selecting its declaration location and rejecting collisions or capture risks.
Submit the example or replace it with your own input. Source is parsed but never executed.
Explicit static behavior
Text replacement cannot distinguish a binding reference from a string or unrelated property key. This route operates on Babel bindings instead.

A rename targets the binding declared at the selected one-based line and column. It is rejected when the destination already exists in that declaration scope or would capture a reference.
Tool Swim parses source as standard ECMAScript inside a disposable Web Worker with a 2,000 ms deadline. It never calls eval, Function, imported modules, or user code.
Source and results stay in the current browser tab. The public tool makes no API request, stores no preset, and does not require an account or telemetry.
