🔥 Regular Expression Improvements

ES2025 also introduced improvements to regular expressions, including support for enhanced Unicode-related matching capabilities.

🔥 Promise.try()

Promise.try() provides a convenient way to turn a synchronous function call into a Promise-based operation.

Promise.try(() => {
return someFunction();
});


⚠️ Important Interview Point

JavaScript features are standardized through the ECMAScript specification, and browser/Node.js support can vary by feature and version.

So when discussing "latest JavaScript," distinguish between:

Standardized features

→ Officially included in an ECMAScript release.

Proposed features

→ Still moving through the TC39 proposal process.

Runtime support

→ Whether a particular browser or Node.js version actually supports the feature.
