JavaScript array-like, iterator-like, property-like, constructor-like things (2026)

JavaScript-like things

i think we need a new jargon in js. “constructor-like” thing. e.g. the BigInt() and Symbol(), because they feels like constructors but technically are not.

• rhyme with “array-like” (Array.isArray false)
• “iterator-like” (iterators not descentant of Iterator.prototype)
• “property-like” (private fields in class).

• JS: Symbol Tutorial
• JS: BigInt constructor-like function
• JS: Array-Like Object
• JS: iterator-like object
• JS: class (keyword)
