JS Code Snippets Classes

Javascript Classes

In this code snippet, we’ll learn about classes in Javascript. Classes were introduced ES6. They work the same way they do in other languages and act as templates to make objects from. Again I will just demonstrate how to use classes in javascript and won’t go into specifics of OOP(I already did some posts about it in C#).

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.
