Working in technology is a dream for many young people who have an affinity for the field. After all, there's no shortage of good opportunities in large companies\u2014in addition to above-market salaries. Do you identify with this scenario? Then you should know that mastering programming languages is fundamental to success in this field. career<\/a>.<\/p>

However, you probably know that there are many existing programming languages to meet the demands of companies and bring so many systems and applications to life. This raises questions about how to learn them most effectively and what the market expects from technology professionals.<\/p>

With that in mind, we've prepared this guide to help you understand the main programming languages that exist today, how to learn about industry trends, and how to master them. Let's get started?<\/p>

The history of programming languages<\/h2>

The history of programming languages is quite long and began many decades ago\u2014and it's not our intention to recount it in detail here. However, it's interesting to have a brief overview of humanity's first steps in engaging with technology to understand its purpose.<\/p>

Firstly, it's worth highlighting that its history is directly related to the emergence of the first intelligent machines: through them, the aim has always been to transform logical sequences into solutions to problems. This leads us to the Frenchman Joseph-Marie Jacquard, who created a loom capable of replacing man in his production process.<\/p>

It was by observing this machine that Ada Lovelace created algorithms that were interpreted by the first computer in history (developed by Charles Babbage). Thus, the concept of programming languages began, and gradually, scholars in the field realized that several of them would be needed to solve different problems.<\/p>

As you may have seen in the film The Imitation Game, Alan Turing was also very important in understanding the importance of intelligent machines, further solidifying the foundation for the functional computer we know today. At that time, programming languages worked with codes of 0 and 1, which made life complicated for professionals.<\/p>

In the 1950s, Assembly emerged, the language that most closely resembles that of machines, but which, even so, already facilitated human understanding. Its creation sparked the interest of these scholars, who saw the opportunity to further humanize these codes. Soon, Fortran, Lisp, and Cobol followed.<\/p>

Already in the 1970s, some languages were created that are still used today, such as C (which we will learn more about later). From that point on, many others derived from C, paving the way for the technological evolution that made possible... Industry 4.0<\/a> that we are experiencing today.<\/p>

The main types of programming languages<\/h2>

Now that you understand a little more about the emergence of programming languages, it's time to learn about the main ones currently on the market. Pay attention, because... professional of the future<\/a> You must know at least one of them.<\/p>

Java<\/h3>

This object-oriented language emerged around 1995, promising to be fast, secure, reliable, and cross-platform. This is because programs created in Java are not written in native platform code. Instead, they are compiled into an intermediate form called bytecode and executed through a virtual machine.<\/p>

In this way, a programmer who develops a system in Java performs this process only once, and can later run it on any platform that supports the language.<\/p>

When you need to access your virtual bank account on a computer or even some applications from the Brazilian Federal Revenue Service, you are in contact with the greatest examples of the application of this technology.<\/p>

A common myth in the tech market is that this programming language is difficult to learn. However, the difficulty often arises due to object-oriented concepts, which may not be clear to professionals. Understanding this particularity opens the sky's the limit for the professional.<\/p>

JavaScript<\/h3>

According to a Stack Overflow search<\/a>, JavaScript is the most used programming language by the programmers in the sample, exceeding 69%. With it, it is possible to make all developed functions come to life for users \u2014 that is, it handles all visual interactions with the platform or system.<\/p>

You know when you open a photo album and can interact with the pages, as if you were handling a book? Or when you navigate a map, zooming in or out to access better images? These are prime examples of JavaScript.<\/p>

Python<\/h3>

Despite existing for decades, the Python<\/a> It has gained popularity in recent years. Its main objective is to improve system readability and productivity, with easily maintainable code and a low number of special characters.<\/p>

If you dream of working at Google someday, know that programming in Python is a fundamental requirement\u2014and, interestingly, at NASA as well. Besides being a high-level language, it boasts a vast library and excellent frameworks, making the professional's life easier.<\/p>

C programming language<\/h3>

If you've ever started a technology course, you've certainly come into contact with C. It's quite common in academia, as it gives rise to several programming languages, such as C++ and C#. Students use it to learn the logic of algorithm creation, as it's intuitive and easy to learn. It's not necessary to set up a local environment on the machine to run it\u2014after all, most operating systems already use it as a base.<\/p>

Many say that it's possible to do almost anything in C, although it's not the ideal language for all applications. One of its characteristics is modularity: it consists of various blocks where functions are not interconnected. The best-known example of its use is the Linux operating system.<\/p>

PHP<\/h3>

When we talk about websites, PHP is certainly one of the most requested languages. You've heard of Facebook and WordPress, haven't you? They are the best examples of their applications on the market today. Because it's open source, many professionals have already contributed to improving it.<\/p>

PHP is also rich in frameworks, which help in software development, simplifying it. Among the most used in the market are:<\/p>
