What we’re about
Founded in 2013, [tim.js](https://timjs.ro/) is the local JavaScript Community in Timișoara, Romania.
Its main purpose is to bring JavaScript enthusiasts together and facilitate knowledge sharing between its members through meetups, workshops, and conferences, such as [revo.js](https://revojs.ro/).
Join us on Discord as well.
We welcome everybody interested in any aspect of the JavaScript ecosystem, whether they're a beginner who just started learning, or an expert with decades of experience.

Beyond Copy-Paste: Understanding LLMs and Making Them Work for You
-- Adrian Faciu, Principal Engineer @ WeVideo
Like most developers, I have copied code from ChatGPT or debugged with Claude. But there's a big difference between copy-pasting answers and understanding how to really work with LLMs. The difference? Understanding what's actually happening under the hood.
In this two-part talk, we'll go through the main steps of building a large language model. We'll explore what pre-training means, why tokens matter, what the context window actually is, and how LLMs "think" and use tools like web search or code execution. Knowing why a model hallucinates helps us understand how to treat it. Knowing how it's trained helps us know when to trust the results. This isn't academic curiosity—understanding the internals directly impacts how effectively we can use these tools.
In part two, we will look at practical development practices. When "vibe coding" actually works, how to manage context, when to use specialized agents, how to leverage MCPs, and the patterns that separate copy-paste developers from those who truly augment their development process with AI.
We'll focus on the high-level concepts that matter for daily development work. This isn't about building your own LLM or diving into transformer architecture—it's about practical understanding for everyday developers.
