New Instance field syntax

Question

In the following class which makes use of the new instance field syntax:

class Range2 {
    default = 77;
    constructor(from, to) {
        this.from = from;
        this.to = to;
    }

Does this get end up acting the same as:

class Range2 {
    constructor(from, to) {
        this.from = from;
        this.to = to;
        default = 77;
    }

And do all variables outside a function get hoisted to the top of the class, or how does that work?
