In terms of the specification: JavaScript's way of handling local variables is quite different from the way C does it. When you call a function, amongst other things alexical environmentfor that call is created, which has something called anenvironment record. To keep things simple, I'm goin...
This creates a new object in the heap and a reference to it in the stack. References are a core concept of how JavaScript works. Going more into detail here would be out of the scope of this article, but if you want to learn more about it, let me know in the comments andsubscribe...
The main concept that garbage collection algorithms rely on is the concept ofreference. Within the context of memory management, an object is said to reference another object if the former has access to the latter (either implicitly or explicitly). For instance, a JavaScript object has a referen...
Binary data, while ubiquitous and a first-class concept in many traditional programming languages like C, can be easy to misunderstand, especially for developers using high-level languages such as JavaScript. Just in case you haven’t had experience with it, binary is a system of counting that...
which is sharing memory between two threads. In order to do that we will need to use a new data structure available globally which is calledSharedArrayBuffer. This shared buffer is the memory itself and a typed array on top of that memory area works like a view. This concept is really si...
KNOWLEDGE: In LangChain, the concept of chains refers to a sequence that may include interactions with an LLM, utilization of a specific tool, or a step related to processing data. To effectively construct these chains, it is advised to employ theLangChain Expression Language(LCEL). Withi...
ts-nodehas no concept of on-disk caching. This is a deal breaker for us.Then why not contribute this feature to ts-node?. Well, we can. But in order for caching to work properly, the module need to expose the helpers for watchers to cleanup the cache and I don't think, ts-node...
So naturally, we'd expect memory usage to be higher when a framework that uses this concept is in place. And, unsurprisingly, that's exactly what we see. There's a risk of looking at that table and immediately deciding that using React, for example, is terrible for memory while ignoring...
In-Memory Database Engine for JavaScript Concept dbjsis database of events, each atomic update is represented as an event which is added on top of log. In contrary to popular CRUD model, each creation, update and deletion is just another atomic event that occurs and affects state of things...
The Resident Set contains also the actual Javascript code (inside the Code segment) and the Stack, where all the variables live. Hopefully the following illustration will clarify the concept: Sounds complicated? We need to focus only on the heap for now, so don't worry if you can't grasp...
