2. TIPOS DE DATOS PRIMITIVOS en JAVASCRIPT | JS en ESPAÑOL

PRIMITIVE DATA TYPES is #2 of the 33 CONCEPTS YOU SHOULD KNOW if you want to WORK PROFESSIONALLY with JavaScript. Many people mistakenly believe that data types don't exist in JavaScript because we can first assign a number to a variable and then a string, and we won't see any errors in our program. Due to their specific characteristics, there are two main groups of data types in JavaScript: PRIMITIVE DATA TYPES and OBJECTS. In this video, we'll talk in detail about PRIMITIVE DATA TYPES in JAVASCRIPT. We'll learn what PRIMITIVE DATA TYPES are and what their characteristics are. We'll also see what PRIMITIVE DATA TYPES exist and how and why each one is used. We'll answer one of the questions we'll all ask ourselves sooner or later if we program in this language: WHAT IS THE DIFFERENCE between NULL and UNDEFINED? I'm also going to tell you about a BUG that's part of JavaScript. Yes, the language has bugs... and this is one that can't be fixed. And finally, we'll talk about a new PRIMITIVE DATA TYPE coming in future versions of JavaScript. So I recommend you watch the video until the end to learn more.
