JS Code Snippets Objects

Javascript Objects

In this code snippet, we’ll learn about objects in Javascript. Objects can contain other objects, functions, properties and act as a sort of container for them. This is useful for transferring/storing data, modeling real world objects and for grouping a certain set of related functions and variables into one place.

JS Code Snippets JSON

Javascript JSON

In this code snippet, we’ll learn about JSON serialization/deserialization in Javascript. JSON or javascript object notation is a data format/structure for storing/transporting data. It’s supported by a wide variety of programming languages. It’s short, concise, easy to read/write and understand.

In Javascript, you can use the JSON.stringify() method to turn an object into a JSON string and JSON.parse() to turn a JSON string into an object.

JS Code Snippets const Keyword

Javascript const Keyword

In this code snippet, we’ll learn about the const keyword in Javascript. The const keyword does almost exactly the same thing to a variable as the let keyword. You can read more about let in this post. The difference is it also makes the variable a constant meaning it can only have its value assigned once.

JS Code Snippets let Keyword

Javascript let Keyword

In this code snippet, we’ll learn about the let keyword in Javascript. Javascript allows for some pretty weird stuff with variables like using them before being declared, declaring the same variable, multiple times and no variable scope.

JS Code Snippets For Of And For In Loops

Javascript For Of And For In Loop

In this code snippet, we’ll check out the for of loop in Javascript. You probably already know about the for and while loops. But there is another very useful type of loop present in Javascript called the “for of” loop. It can be used to iterate throught iterable object. I would say it’s the quivalent of the foreach loop in C#.

PHP Sending Emails

In this code snippet, we’ll learn how to send emails with PHPMailer in PHP. First, we’ll need to install the PHPMailer package. We’ll do that using a dependency manager for PHP called Composer. (See this tutorial if you want to know how to install Composer in the first place.)
