Uncaught exception when inspecting a logical asignment

[acarstoiu]

Here is a file submitted to JSHint 2.13.1:

let a;

a ??= 235;

Indeed, JSHint configuration accepts at most "esversion": 11 and such an assignment is specified in ECMAScript 12 (2021), see here. But JSHint crashes with:

        ^

If this is regarded as a request to support ES 2021, then so be it.

Hi there! JSHint mostly tracks language support at the granularity of individual features rather than revisions of ECMAScript. Since support for logical assignment has already been requested via gh-3544, I'm going to close this issue to keep things organized.
