JavaScript has several built-in data types: String (text), Number (numeric values), Boolean (true/false), null (intentional absence), undefined (no value assigned), and Symbol (unique identifiers). Each type has specific behaviors and uses. For instance, Boolean evaluates conditions, while Symbol prevents property conflicts in objects. MORE q

JavaScript has many ways to compare data. There are both strict and pliant comparisons avaialable Strict comparisons require the type of the data as well as the values be identical. For this, a number can only match a number and they must have the same value, a string only matches another string with the same value, etc. The more pliant comparisons check for a match to the data value, and does not care about the MORE q

JavaScript is decently equipped to get a handle on errors that may arise. The first tool we should know is the Error Object. const myError = new Error('Oh No!'); throw myError.name + myError.message + myError.stack; Built-in Error Objects are numerous. A complete MORE q

Conditional Statements test a claim and then either run a block of code or pass to the next step. Ultimately, these statements provide dynamic programmed responses where data can be set programmatically or change, like in the case of user input, and the JavaScript code can respond in different programmed ways. Conditional Statements: if - When a condition is met, run a block of code. else - When a condition is not met in an if statement, run a different bloc MORE q

There are a large number of methods that JavaScript includes as part of the various Objects that are built automatically. The previous article, JS Methods, gave an introduction to methods and detailed some of the more commonly used. There are many more, of course. Every JavaScript method is listed here. This is sorted by object so we can see what is available when working with any specific one. These objects will usually inherit methods that will work on the object, but, are not exclusive. In the list below, these inherited methods can be toggled on or off. When toggled off, the inherited methods will be MORE q

A method is a ultimately the same as a function in that it is a block of code that performs an action. The difference between a method and a function is that a method is a property of an object. that performs actions on that object. Invoking a function and calling a method are a little different. For a function, you only need the function name and parenthesis. For a method, we need to identify where the method is located first, MORE q

Functions are pieces of code that perform actions. There are both functions built into JavaScript and an almost limitless number of functions a developer can create. The Anatomy of a Function Function can be created using the function keyword, usually followed by a unique name, though a name is not required, followed by () and then { } Inside of the (), you can set perimeters. These perimeters ore optional, but, if used, allow for data to be transferred in to the function to be used. Functions usually end with the keyword return. This keyword signals the JavaScript engine to stop processing the function and will take MORE q
