What type of language is JavaScript considered to be?

JavaScript is considered an interpreted language because it is executed line by line by an interpreter at runtime rather than being compiled into machine code beforehand. This allows developers to run their scripts in a web browser or other environments immediately without the need for a separate compilation step.

In practical terms, this interpretive nature allows for greater flexibility and immediate feedback during development, making it possible to test code snippets quickly. JavaScript engines, such as those in web browsers, read and execute the JavaScript code directly, which contrasts with compiled languages that require the entire codebase to be converted into executable files before running.

Furthermore, being an interpreted language aligns with its use in dynamic web pages where scripts can be modified and delivered by the server, facilitating real-time interaction without requiring page reloads. This characteristic is a core aspect of JavaScript's functionality in web development, enhancing user experience through responsiveness and interactivity.
