Is the following a correct usage of JSDoc on a class? The code is trivial but I'm more interested in if this is an idiomatic usage of it or I'm missing somethings:

class Person {

    /**
     * Create a Person
     * @param {string} name
     * 
     */
    constructor(name) {
        this.name = name;
    }

    /**
     * Print a salutation for that person
     * @returns {number} The number 1 if successfully invoked
     */
    say_hello() {
        console.log(`Hello ${this.name}`);
        return 1;
    }

}

Additionally, I'm using VSCode, are there extensions that help with creating this boilerplate?
