javascript - How to use the feature of directly declaring attributes in js class in babel

Question

Such a class:

class TestClass {
    name = 'abc';   //直接声明在class中
    static staticValue = 456;   //这是静态属性
    showName() {
        console.log(this.name);
    }
}

let cls = new TestClass();
cls.showName();

Is the above syntax supported in es? How to configure it if babel is used for translation?

Answer 1

Static attributes should be remembered as an ES7 proposal.
It seems that babel-stage2 will work. I don’t remember it clearly. You’ll know if you try it.
