## about this topic

Programming languages are the interface between human reasoning and the machine — and choosing (or mastering) the right one changes the trajectory of a career. This hub holds the CodeCrush articles on languages: complete guides to Python, JavaScript, Java, C, Ruby, R and PHP, comparisons between the languages most used in the market, and practical resources for learning and practising each of them. Every guide covers what the language is for, where it is strong, the ecosystem of libraries and frameworks around it and the corresponding job market. Use this page as a starting point to decide which language to learn next, or to go deeper into the one you already use every day.
