Description

Ensure that variables and properties names use camelCase and not snake_case or PascalCase.

Non-Compliant Code Examples

var a = {
    MyProp: "should be camelCase",
    foo_bar: 0,
    #Priv: 2,
};
const my_var = {};
let FooBar = {};
const { a_b, ...Bla } = c;
const [a_b, ...Bla] = c;

const _bad_name = 200;

Compliant Code Examples

/* The BenefitsDAO must be constructed with a connected database object */
function BenefitsDAO(db) {

    "use strict";

    /* If this constructor is called without the "new" operator, "this" points
     * to the global object. Log a warning and call it correctly. */
    if (false === (this instanceof BenefitsDAO)) {
        console.log("Warning: BenefitsDAO constructor called without 'new' operator");
        return new BenefitsDAO(db);
    }

    const usersCol = db.collection("users");
    const Users = db.collections("something");

    this.getAllNonAdminUsers = callback => {
        usersCol.find({
            "isAdmin": {
                $ne: true
            }
        }).toArray((err, users) => callback(null, users));
    };

    this.updateBenefits = (userId, startDate, callback) => {
        usersCol.update({
                _id: parseInt(userId)
            }, {
                $set: {
                    benefitStartDate: startDate
                }
            },
            (err, result) => {
                if (!err) {
                    console.log("Updated benefits");
                    return callback(null, result);
                }

                return callback(err, null);
            }
        );
