Desktop apps, mobile apps, and web apps. Apps are everywhere. In the past years, as hardware became more powerful, the tendency to merge apps between desktop, mobile, and web platforms is higher than ever. And, in accordance with that, we meet more and more programming languages and frameworks that we can use on every platform with a minimal trade-off in terms of code difference, app execution speed, and even user interface.
In this article, we are going to answer the question of how to make a (mobile) app as a total beginner. The answer requires a multi-faceted approach, starting with the perspective of the person that is asking that question. Are you an aspiring developer who wants to learn how to develop an app? Are you an eager product manager? Or are you an ambitious startup owner?

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.

“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.

This is simple question and may sound like the answer is also simple. However, there are few things you need to take into account when creating variables and assigning values just to be sure you’re not overwriting existing variables. It’s even more important in complex projects with multiple modules because it’s sometimes hard to keep track of each variable and their scope.
