ES has all of those things except for requiring that a statement ends with a semicolon.

ES has all of those things except for requiring that a statement ends with a semicolon.
- Widdershin 11y agoI would disagree that ES has classical inheritance. ES6 has syntactic sugar over prototypical inheritance that resembles classical inheritance in other languages, but it's still prototypical under the hood.
- colbyAFTrustedK 11y agoIs there a meaningful ? I.e., what does classical inheritance get you that prototypes-under-the-hood don't? For a programmer using classes, that ES's are implemented using prototypes should be as important has how the JVM works.
- robocat 11y agoClassical inheritance enforces that a method can only be overridden by another method in a subclass. Prototypical "inheritance" allows different types of values to be assigned to the same symbol. E.g. if you have a method bob() on a prototype, you can set object.bob = 'astring'; and it isn't an error.
- colbyAFTrustedK 11y agoThat has more to do with a language opting out of having fixed types than it does with class-based versus prototype-based inheritance.
