JavaScript programming language

Back to DuckDB Data Engineering Glossary

JavaScript is a versatile, high-level programming language primarily used for web development. It enables dynamic, interactive content on websites and runs in web browsers, making it an essential tool for front-end developers. JavaScript has evolved beyond its initial purpose and is now used for server-side programming (Node.js), mobile app development (React Native), and even desktop applications (Electron). Its syntax is C-like, and it supports multiple programming paradigms, including object-oriented, functional, and imperative styles. For aspiring data analysts and engineers, JavaScript is valuable for creating interactive data visualizations, building web-based dashboards, and developing data-driven applications. Popular libraries like D3.js allow for complex data visualization, while frameworks such as Vue.js and React enable the creation of sophisticated user interfaces for data applications.
