What programming language is used in Playwright?

Playwright supports multiple programming languages, including JavaScript, TypeScript, Python, Java, and C#. However, JavaScript and TypeScript are the most commonly used because Playwright was created by Microsoft with a strong focus on modern web development.
Java and Python with Playwright at Credo Systemz are also gaining popularity, especially in companies transitioning from Selenium. The flexibility of language support makes Playwright attractive for testers from different backgrounds.
