~javascriptweekly | Issue 699 - How Googlebot sees your JavaScript (14)

How Google Handles JavaScript In Its Indexing Process — Once, if you wanted Google to index your content, it needed to be right in the HTML and not dynamically rendered with JavaScript. Things have changed, but how much? MERJ and Vercel analyzed over 100,000 Googlebot fetches in an attempt to empirically demystify Google’s approach.

Garbage Collection and Closures — When three JavaScript experts get together and all learn something new about how JavaScript works when they encounter a memory leak, it pays to listen. An interesting quirk to be aware of.

Announcing TypeScript 5.6 Beta — The first beta of the next major version of TypeScript is out. Region-prioritized diagnostics (VS Code only, for now) is a particularly interesting addition.

Benchmarking AWS Lambda Cold Starts Across JS Runtimes — It’s from the Deno team so it may not be surprising that Deno was fastest, but they share their methodology and results for Deno, Node, Bun and AWS’s managed Node runtime and they weren't all that far apart.

Node.js's Experimental Support for TypeScript — In this pull request, Node merged an experimental ability to transpile TypeScript into JavaScript, ultimately letting Node directly ‘run TypeScript’. No type checking is performed and, as Matt Pocock explains, TypeScript-only features are a no-go.

Ever Felt Compelled to Answer with Certainty When You Weren’t Sure? — Don’t stifle innovation with this toxic behavior. Thoughts on how to fix this—as a leader or individual contributor.

A Different Way to Think About TypeScript — “a very expressive way to operate over sets, and using those sets to enforce strict compile time checks”
