JS – Types & Grammar
Most developers would say that a dynamic language (like JS) does not have *types*. An ECMAScript language type corresponds to values that are directly manipulated by an ECMAScript programmer using the ECMAScript language.

JavaScript defines seven built-in types: null undefined boolean number string… Continue reading JS – Types & Grammar
JS – OOP
Object Oriented Programming (OOP) refers to using self-contained pieces of code to develop applications. We call these self-contained pieces of code objects, better known as Classes in most OOP programming languages and Functions in JavaScript. We use objects as building blocks for our applications. Building applications with objects allows us to adopt some valuable techniques,… Continue reading JS – OOP

The following built-in types are available: string number boolean null and undefined object symbol (new to ES6) JavaScript provides a `typeof` operator that can examine a value and tell you what type it is: typeof null is an interesting case,… Continue reading JS – UP and Going (chapter 2)
