In Javascript, and in any other programing language, functions are one of the most important building blocks. Basically, you can’t do anything without them, therefore it is super important to know as much as possible about them. This article will take you into the world of Javascript functions – you will learn (almost) everything you need to know about them. Let’s get started.
…

In this article, you will get to know the innerHTML property of the HTML DOM and how is connected to JavaScript.

Loops are a beautiful thing – they can cut down lines and lines of your code because loops are used to avoid repeating a block of code. Therefore, if you want to run one code time and time again, but each time with a different value, use a loop. Want to repeat some message 10 times? Use a loop.

This article is going to take you into the world of the “finally”. We will take a look at how to handle the try/catch/finally blocks, but we will also learn more about the Promise and a finally() method.

The boolean logic is named after George Boole, who is the pioneer in the field of mathematical logic. At the very core of boolean logic is the idea that all values can be either true or false, and this has been translated into computer science as booleans – a logical data type that can only have two values, either true or false, on or off, yes or no, etc. In this article, we’re going to look into booleans basics, we will get to know the concept of falsy and truthy values, and at the end, we will get to know what boolean() object is all about.

In this article, we will explore the eval() method. We will get to know the syntax and explain what is the purpose of the method. We will explore whether eval() is really evil and whether you should really stop using it. And if it’s not, are there any legitimate reasons when you should use the eval() method.

In JavaScript “else” keyword is a part of conditional statements that we use to perform specific actions which are based on different conditions. There are two conditionals that use the else keyword in their statements – “else” and “else-if”. In this article, we will explore the world of these two conditionals – when to use them, should you stop using them, and whether there are better alternatives available.

“Do” is another reserved keyword in JavaScript that cannot be used as a variable, label, or function name. However, this reserved keyword cannot stand alone and is closely connected to another reserved keyword – “while”. Together “do” and “while” keywords create a loop and in that loop, the do keyword executes (does) some part of the code. Let’s go through a few examples and see what is the purpose of the “do” keyword in the do-while loop.
…

Delete. The sole purpose of this keyword is quite self-explanatory – we want to delete “something”. But what can we delete? And do we really delete “that” or can we read it again? This article will take you into the world of the delete operator in JavaScript – you will learn what you can and cannot delete and what exactly the delete operator in specific situations really means?

You will make errors. Your scripts will have errors, no matter what. These errors can be in relation to syntax or logic. And often it will be a case, that you won’t see any error messages and you’ll have no clue where exaclty you should look for errors. This is where code debugging comes into place. Luckily, all browsers have JavaScript debugger built-in and it can be turned on or off, which dictates whether script errors are reported to the user. You can also set breakpoints and check variables during the code execution. In short, Debuggers go through the entire code and they identify these errors and also fix them.
