Start with hello world. Use Node to run your JavaScript programs. Ideally, use Jasmine to write test harnesses. Here's a heads-up: It's not OO like you know itIt has no private keyword: you use function closures to do thisThere are no classes, except in ES6. They are not totally the same as C++ classesThe 'this' pointer can be reassigned. It has different rules to those in C++Variables declared with var do not have block scope like in C++, and their type can be changed at willType coercion rules are woolly== tests for 'roughly equals' You need === for exact checksnull, undefined, zero and NaN differ in behaviourExceptions are untyped. There are no destructorsIt's memory managed, new does not need deletedelete exists but is not the same as in C++There are no collection classes.There are a lot of callbacksFunctions are JavaScript objects, and this is really good. Functions start a closure which is a unit of scope and encapsulationThere are three ways to make an objectObjects have prototypes, and inheritance is done that wayThere are no interfaces. You call methods and they either work or fail read less

JavaScript is really easy you just need to have a look at the syntax and I am sure you understand it if you have good hands in C++. Even popular runtime environment like node js uses C++ as the core.
