babel
ES6
javascript
<p>La vérité si je mens, Babel c’est bien ! Agade ce simple code en ES6 :</p>
<pre class="brush: js">'use strict';
class Vehicle {
constructor(brand) {
this.brand = brand;
}
}
class Car extends Vehicle {
constructor(brand,model) {
super(brand);
this.model = model;
}
}
let myCar = new Car('Mercedes','300SL');
console.log(myCar);</pre>
<p>Converti en version 5 par Babel :</p>
<pre class="brush: js">'use strict';
var _get = function get(_x, _x2, _x3) { var _again = true; _function: while (_again) { var object = _x, property = _x2, receiver = _x3; desc = parent = getter = undefined; _again = false; if (object === null) object = Function.prototype; var desc = Object.getOwnPropertyDescriptor(object, property); if (desc === undefined) { var parent = Object.getPrototypeOf(object); if (parent === null) { return undefined; } else { _x = parent; _x2 = property; _x3 = receiver; _again = true; continue _function; } } else if ('value' in desc) { return desc.value; } else { var getter = desc.get; if (getter === undefined) { return undefined; } return getter.call(receiver); } } };
function _inherits(subClass, superClass) { if (typeof superClass !== 'function' && superClass !== null) { throw new TypeError('Super expression must either be null or a function, not ' + typeof superClass); } subClass.prototype = Object.create(superClass && superClass.prototype, { constructor: { value: subClass, enumerable: false, writable: true, configurable: true } }); if (superClass) Object.setPrototypeOf ? Object.setPrototypeOf(subClass, superClass) : subClass.__proto__ = superClass; }
function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError('Cannot call a class as a function'); } }
var Vehicle = function Vehicle(brand) {
_classCallCheck(this, Vehicle);
this.brand = brand;
};
var Car = (function (_Vehicle) {
_inherits(Car, _Vehicle);
function Car(brand, model) {
_classCallCheck(this, Car);
_get(Object.getPrototypeOf(Car.prototype), 'constructor', this).call(this, 'Mercedes');
this.model = model;
}
return Car;
})(Vehicle);
var myCar = new Car('Mercedes', '300SL');
console.log(myCar);</pre>
