The role of the English language in IT is huge and not accidental: most modern technologies, programming languages and frameworks were originally developed by English-speaking engineers. For this reason, all the key terms, function names, and even the syntax of most programming languages are in English. For example, commands such as if, else, return, print, and function are used in almost all popular programming languages, from Python to C++. You need to understand these terms at least at a basic level to write code. In addition, English is used for technical documentation, which is available in any programming language, library, or tool. Without knowledge of the language, it will be difficult for a programmer to understand new technologies or reports if there is no translation.
