 **Goal:**
 Restrict usage of some Javascript language features known to be slow after the _COMPAT_ transformation. LWC runs in _COMPAT_ mode on older browsers (eg. IE11). To support new Javascript syntax and language features on older browser the LWC compiler transforms LWC modules. This linting configuration targets patterns known to be slow in _COMPAT_ mode.
