Highlight global variables
NiedziolkaMichal opened this issue · 1 comments
There are 4 global properties in JavaScript: undefined
, NaN
, Infinity
& globalThis
. All of those are unique in the language, they have special features and undefined is also a primitive value. Current highlight.js treats them as variableName
, because of which they share color with any other variable. Would it be possible to put those 4 values under a unique tag, so they can have a different style than rest of the variables? Two of those: undefined
& NaN
could easily share tag with null
.
Not really, because they can be shadowed (function(undefined) { return undefined + 1 }
), so a parser that doesn't track scopes can't really distinguish them from regular variable names. As such, I've decided to not parse them specially.
