Converts underscore property names into computed property names backed by a private symbol.
The following code:
class Point {
constructor(x, y) {
this._x = x;
this._y = y;
}
toString() {
return `<${ this._x }:${ this._y }>`;
}
add(other) {
return new Point(this._x + other._x, this._y + other._y);
}
}is transformed into:
var _x = Symbol.private('x'),
_y = Symbol.private('y');
class Point {
constructor(x, y) {
this[_x] = x;
this[_y] = y;
}
toString() {
return `<${ this[_x] }:${ this[_y] }>`
}
add(other) {
return new Point(this[_x] + other[_x], this[_y] + other[_y]);
}
}
