In this code snippet, we’ll learn how to handle errors in Javascript. You can throw errors by using the throw keyword. Then you can catch them using the try catch block. If you want to catch errors globally you can use the window.onerror event to call your error handling function.
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#).
In this code snippet, we’ll learn how to use the bitwise operators in Javascript. Bitwise operators allow us to work and manipulate the actual bits.
In this code snippet, we’ll learn how to check and convert data types in Javascript.
In this code snippet, we’ll check out some of the Math class functions in Javascript. More information about all the functions and constants here.
In this code snippet, we’ll learn how to sort and reverse arrays in Javascript.
In this code snippet, we’ll learn how to use some of the Javascript string manipulation functions.
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.
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.
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.
