proposal-bind-operator VS proposal-class-fields

There was also a different proposal that allows objects to be extended: https://github.com/tc39/proposal-bind-operator

Personally, I don't use classes much, but sometimes I think free functions a little bit hard to find, so I tend to experiment with the following pattern.

interface User { … }

const User = {

Yangi bind operatori Function.prototype.bind ni yanada elegant tarzda ishlatish imkonini beruvchi yangi sintaksis

In modern JS, you can export each function directly without putting them in an object. It also allows you to call a function with a specific “this” value, function.bind(object)(args). As a matter of fact, there’s a syntax proposal proposal and to do exactly this, object::function(args). This proposal could make what you describe pretty popular.

Hey, not yet ;)

This binding syntax (::)

You'd need 4 periods.

I don't think you want realms so much as protocols or extensions, the latter assimilating the beloved bind operator.

Private methods: Pretty simple to explain, private methods and fields straight up do not work with ES6 proxies, its a known issue https://github.com/tc39/proposal-class-fields/issues/106

The #x syntax is ugly and many people don't like it. But if you understand how JavaScript works, you'll see that private x is not possible. Some comments on the proposal suggested private #x and there were plenty of other suggestions as well, it may be interesting to read through those discussions.

> - # private... not sure why they didn't just use the "private" keyword, but I don't care. I almost always use TypeScript anyways

One of the reasons was to allow private and public fields of the same name, so that subclasses are free to add own public fields without accidentally discovering private fields. There were many more considerations that went into the design: https://github.com/tc39/proposal-class-fields/blob/main/PRIV....

There was a heated debate about this and the choice of the # sigil back in 2015 at the time private fields were being designed: https://github.com/tc39/proposal-private-fields/issues/14.

class App extends React.Component { constructor(props) { super(props); this.state = { counter: 0 }; }} but due to Babel's class-field support, I don't use it anymore

I am using ReactJS with Babel and Webpack and using ES6 as well as the proposed class fields for arrow functions. I understand that arrow functions make things more efficient by not recreating the functions each render similar to how binding in the constructor works. However, I am not 100% sure if I am using them correctly. The following is a simplified section of my code in three different files.

Working with constructor and calling super() before we can set state. Although this has been solved with the introduction of class fields in JavaScript, Hooks still provide a simpler API
