JavaScript Execution

Definition ∞ JavaScript execution refers to the process by which web browsers or other runtime environments interpret and run JavaScript code. This client-side scripting language enables dynamic and interactive content on websites and web applications. Proper JavaScript execution is essential for the functionality of many decentralized applications (dApps) and crypto trading interfaces. However, vulnerabilities in JavaScript can be exploited for malicious purposes.
Context ∞ JavaScript execution is a fundamental aspect of modern web interfaces, including those used for interacting with digital assets and blockchain applications. News in cybersecurity often highlights how vulnerabilities in JavaScript, such as cross-site scripting (XSS) attacks, can compromise user wallets or redirect transactions. Ensuring secure JavaScript practices and regular security audits is crucial for protecting users in the crypto ecosystem.
