Interview with a female programmer:

Who are Programmers?
Programmer is referred to as a software developer, software engineer, programmer, or coder, and is a person who creates computer programs — often for larger computer software. A programmer is someone who writes/creates computer software or applications by providing a specific programming language to the computer. Most programmers have extensive computing and coding experience in many varieties of programming languages and platforms, such as Structured Query Language (SQL), Perl, Extensible Markup Language (XML), PHP, HTML, C, C++, and Java. A programmer's most often-used computer language (e.g., Assembly, C, C++, C#, Javascript, Lisp, Python, Java, etc.) may be prefixed to the aforementioned terms. Some who work with web programming languages may also prefix their titles with web.
What is the role of programmers?
As far as understanding is concerned, computer programmers design, develop and test software and ensure software adheres to best practices in performance, reliability, and security. Computer programmers can work developing mobile applications, coding video games, programming websites, and much more.
Need math to be a programmer?
Don't need to be good at advanced math to become a good software developer. While some fields of programming require you to have extensive knowledge of mathematics (such as game development and machine learning), you don't need advanced math skills for most coding jobs.
What is the most popular programming language right now?
As per StackFlow's and a few programming communities' 2021 surveys, Javascript has been voted the most popular programming language. This was closely followed by HTML, CSS, SQL, and Python.
