Okay loc property isn't supported now by oxc-parser ...

[avivkeller]

Suggested change

	{
	range: false,
	lang: 'js',
	astType: 'js',
	sourceType: 'script',
	}

These are all the default

[AugustinMauroy]

humm yeah right. but range will need to be used since loc isn't available.

[avivkeller]

.start and .end exist on all nodes, regardless of range setting, does Github support that syntax (over L?)

Good to know

does Github support that syntax (over L?)
