The longevity of a programming language depends on many factors, including its relevance to current technological advances, community support, industry adoption, and continuous evolution. While the value of some languages ​​may decrease over time, other languages ​​continue to develop and remain relevant. Here are a few programming languages ​​known for their longevity and maintainability: C: Developed in the early 1970s, C is still widely used, especially in systems programming, embedded systems, and operating systems. Convenience, efficiency and direct access to metal contribute to sustainability. Java: Introduced in the mid-1990s, Java has remained popular due to its independence (via the JVM), strong community support, and widespread use in enterprise applications, Android development, and large systems. Python: Python has become popular since its introduction in the early 1990s. Known for its readability, flexibility and extensive libraries, Python is used in many fields such as web development, computer science, data analysis, artificial intelligence and more. JavaScript: First developed in the mid-1990s, JavaScript is essential to web development and has evolved significantly with Node.js. js extension for server side apps and applications. SQL (Structured Query Language): Popular in the early 1980s, SQL is a relational database management and query language. Its role in information management ensures that it remains up to date. These languages ​​have proven their longevity thanks to constant innovation, adaptation to new technological paradigms, and widespread industrial use. However, the nature of programming languages ​​is changing, and new languages ​​may emerge and be recognized depending on changing technologies and developer needs.
