Javascript Class Variables

I have encountered an error while trying to declare a variable inside of a Javascript class. Here is an example of code. class BaseContainer { constructor(parent){ this.Shell

Solution 1:

Well, you cannot declare variables inside a class. Put it in the constructor if you want to create a property. Also, you must not put semicolons after method declarations (including the constructor).

class BaseContainer {
    constructor(parent) {
        this.someVar = 1;
        this.shell = document.createElement("div");
        parent.appendChild(this.shell);
    }
}
