JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
A simple ES6 class that can be extended to provide macros and getters functionality
Extend
class
prototype in style 😎
Base class for exposing external API to extend the class prototype in a more declarative way.
class Foo {}
module.exports = Foo
Someone can extend it follows.
const Foo = require('./Foo')
Foo.prototype.greet = function () {
return 'Hello!'
}
// or add getter as follow
Object.defineProperty(Foo.prototype, 'username', {
get: function () {
return 'virk'
},
})
import { Macroable } from 'macroable'
class Foo extends Macroable {}
Foo.macros = {}
Foo.getters = {}
export default Foo
import Foo from './Foo'
Foo.macro('greet', function () {
return 'Hello!'
})
Foo.getter('username', function () {
return 'virk'
})
You can see the API is simpler and less verbose. However, there are couple of extra benefits of using Macroable.
Singleton getters are evaluated only once and then cached value is returned.
Foo.getter('baseUrl', function () {
return lazilyEvaluateAndReturnUrl()
}, true) 👈
Using the hydrate
method, you can remove macros and getters added on a given class.
Foo.macro('greet', function (name) {
return `Hello ${name}!`
})
Foo.getter('username', function () {
return 'virk'
})
Foo.hydrate() 👈
Foo.greet // undefined
Foo.username // undefined
