What is the techical reason the JavaScript regex class \w cannot be changed? -


there proposal update regex character classes \w, \d, \b, etc. when used unicode regex flag u (relevant es-discuss thread).

reading thread, arguments presented why \d should not messed with, import of javascript can't cast or coerce non-ascii digit characters numbers. far can tell, same logic doesn't apply \w.

is there compelling technical reason or edge-case i'm not seeing here? after we're talking opt-in flag.

part of reason ask in every other language i'm familiar possible write simple regex matches unicode word character whereas in javascript 1 must specify code point ranges.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
