1 rich Libsyn https://www.libsyn.com 90 600 Will Sentance, educator and co-founder of Codesmith, joins SE Radio’s Adi Narayan to discuss the evolution of JavaScript and modern best practices. They begin with JavaScript's origins as a simple scripting language and its growth into the backbone of modern web development, highlighting the core theme of the &quot;don't break the web&quot; constraint. The requirement that JavaScript must remain backward-compatible has shaped everything from naming decisions (e.g., flat instead of flatten) to the introduction of Symbols as a collision-safe way to extend objects. Will explains how the TC39 group uses the open-source community as a filtration system, absorbing user land patterns (like those from Lodash or Moment) into the standard library only once demand is proven. The upcoming Temporal API is highlighted as a major win for native date/time handling. On the engine side, Will discusses the shift toward monomorphic object shapes in the V8 JavaScript engine for better just-in-time (JIT) compiler performance, and how developers can now write more engine-aware code. The conversation also touches on LLMs in coding: Will's view is that AI tools are useful but risk atrophying developers' under-the-hood understanding, which remains essential for debugging complex, production-scale systems.
