We started with Kotlin, the language of fashion programming in 2019, not because it is the easiest, but because Google has “marked” it as the best programming language for Android.

A few weeks ago it was in the Google I / O when the Mountain View team gave a helping hand to JetBrains, developers of Kotlin, stating that Android will be more and more Kotlin and, therefore, giving more facilities for developers who work with said language.

And yes, exactly the same happens with Javascript, another of the most popular programming languages ​​of 2019, since it is present in the vast majority of web pages.

The same thing happens, many programmers want to get away from Javascript, but the truth is that the web is ” built ” with this language, so it is mandatory to know it (something to which the increase in frameworks such as Angular or React contributes) JS).

        var h1 = document.getElementById ('header'); // contains the reference to the tag <h1>
        h1 = document.getElementsByTagName ('h1') [0]; // accessing the same element <h1>
    </ script>

    <noscript> Your browser does not support JavaScript, or JavaScript is disabled. </ noscript>
</ body>
</ html>

C and C ++

It has years behind him, but it is still one of the most widely used generic programming languages. For video games, for example, is one of the key languages.

It is one of those that everyone who starts doing their first steps in programming starts using, and mastering it is key, although it is not so fundamental anymore.

Rust is a language that took the prize for ” most beloved programming language ” in the survey Stack Overflow developers, so it is clear that if you are interested in the world, you must give it a chance.

It is being developed by Mozilla in a completely open way, so the community is the one that makes it grow (even if it has Mozilla and Samsung itself behind it).

C # or C Sharp is one of the programming languages ​​designed by Microsoft as part of its .NET platform. In fact, it is the programming language of framework.NET and, in addition, it is widely used in video games for all platforms.

Longest comment in a line in Python
'' '

The interesting thing about Python is that we can put comments since the interpreter does not take them into account.


Go is also known as Goland and is a, nothing more and nothing less than, a programming language designed by Google. It is inspired by C, but it is a much more complicated language.

It is focused on very specific processes, but the main objective is security. That’s why Go does not have pointer arithmetic. Being from Google, as soon as it begins to popularize, it surely gains an important gap in the development of Android.
