Webstorm 10中的Ecmascript 6类

Question

I use webstorm 10, and was trying ecmascript 6 with the following code:

/**
 * Class Person
 */
class Person {
    /**
     * Constructor
     * @param lastname
     * @param firstname
     * @param age
     * @param sexe
     */
    constructor(lastname, firstname, age, sexe) {
        this.lastname  = lastname;
        this.firstname = firstname;
        this.age       = age;
        this.sexe      = sexe;
    }

    /**
     * Return the name as string
     * @returns {string}
     */
    toString() {
        return this.firstname + ' ' + this.lastname;
    }

    /**
     * Return true if is an Adult
     * @returns {boolean}
     */
    isAdult() {
        return this.age > 18;
    }

    /**
     *
     * @param {Person} person
     * @returns {*}
     */
    static isAdult(person) {
        return person.isAdult();
    }
}

What I am doing wrong that webstorm tell me that firstname and lastname in toString are unresolved variables, so age and as well isAdult() in the static method?

Answer 1

I bumped into the same problem. In order to fix it you have to supply the @class annotation. This way, it knows it's a class and treats properties as class properties, without warnings.

/**
 * @class Person
 */
class Person {
    ...

You might also want to annotate the properties, like so

/**
 * @class Person
 * @property lastname {String}
 * @property firstname {String}
 * @property age {Number}
 * @property sexe {String}
 */
