JavaScript: Why Is It Important Useful in Cybersecurity? You can create user interfaces and websites that are secure. By preventing cross-site scripting attacks through web forms, and minimizing other risks, you minimize the risk of technical problems. Cookies can be used, event handlers can be manipulated, and cross-site scripting is possible through JavaScript.
