🅰️ #Angular signals 📡 are all the hype and for a good reason!
As with every new thing, it will take time to learn how it works, so there are many misconceptions like...
🤔 Angular signals will make #RxJs obsolete
Let's build a better understanding to find an answer!

The most important difference is that
📡 signals are SYNC, good for
✅ derived state (vs ngOnChanges)
✅ local component reactive state, eg inputs
🔁 #RxJs is used for ASYNC (can be sync)
✅ async orchestration
✅ latest response (race conditions)
✅ cancelation (perf)

Signals & RxJs are optimized for handling different parts of the overall state management
Because of that the optimal real-world solutions will likely include both combined using provided interop
✅ fromObservbale
✅ fromSignal
We can get the best of both worlds!

Generator function* in JavaScript:

In JavaScript, generator functions are a special type of function that allows you to use the yield keyword to pause and resume the execution of the function.
#100DaysOfCode #NodeJS #CodeLife
#100DaysOfCode #NodeJS #CodeLife
They allow you to create iterators, which are objects that can be used to iterate over a sequence of values.
A generator function is defined using the function* keyword and can be invoked using the yield keyword.

Memoization is a technique used to optimize the performance of a function by caching its results for a given set of inputs.
#100DaysOfCode #reactjs #Angular #NodeJS
#100DaysOfCode #reactjs #Angular #NodeJS
The idea is that if a function is called multiple times with the same input, it's more efficient to return the cached result instead of re-computing the result each time.

Data virtualization: With Proxies in JavaScript.
A thread 🧵
#100DaysOfCode #javascript #rarely_used #devbubble
A thread 🧵
#100DaysOfCode #javascript #rarely_used #devbubble
Data virtualization using Proxies in JavaScript refers to the ability to create virtualized data structures, such as virtualized arrays, that load their data on demand rather than loading all data at once.
#100DaysOfCode #ReactJS #Angular
#100DaysOfCode #ReactJS #Angular
This can be useful for improving the performance of an application when working with large data sets.
In this Eg., we create a VirtualArray class that takes in two args- the length of the array & a loader function.

A WeakMap is a map that holds weak references to its keys.
This means that the keys are eligible for garbage collection if there are no other references to them.
This feature can be useful for implementing caches or other similar data structures.

#reactjs #Angular #NodeJS #js
A WeakMap is a special kind of map where keys must be objects and the map doesn't prevent garbage collection of its keys.
You can think of a WeakMap as a map that doesn't "own" its keys, and therefore doesn't keep them alive.

In #Angular Typed Forms, the `get` method takes a string with dot-separated control names, and returns a fully typed value. How is this possible?
We can actually parse the argument at compile time, using the magic of #TypeScript template literal types! Let's see how it works. 🧵

Imagine you have a type listing various products, and you want to automatically generate a type for corresponding database columns.
We define a template literal type called DatabaseColumn. It takes any subtype of string, and maps each element onto a string with a column prefix.
We define a template literal type called DatabaseColumn. It takes any subtype of string, and maps each element onto a string with a column prefix.
The previous example generates a string type by concatenation. However, can we also go the other direction, breaking apart a string type?
The answer is yes! Using the `infer` keyword, we can implement a simple parser. This `ProductFrom` type extracts product names from columns.

If you are still using ng-deep to style child components you really should consider the alternatives.
Host styling, content projection, and CSS variables are all potential solutions for this common problem.
Let’s explore the options below 👇

#Angular
First a couple of words why we need ng-deep in the first place.
In Angular, component's styles are encapsulated within the component's element so that they don't affect the rest of the application.
That has a side effect of making it difficult to style child components.
In Angular, component's styles are encapsulated within the component's element so that they don't affect the rest of the application.
That has a side effect of making it difficult to style child components.
To alleviate this issue, Angular provides an ng-deep selector which pierces the encapsulation of the child component.
All is good then?
Not really, the selector has been deprecated for years and is not recommended by the official docs.

1) First of all, we will begin with installing all the packages we need
npm i web3 crypto-browserify stream-browserify assert stream-http https-browserify os-browserify browser url os-browserify process -S
Then we add this bit of code to the respective files
npm i web3 crypto-browserify stream-browserify assert stream-http https-browserify os-browserify browser url os-browserify process -S
Then we add this bit of code to the respective files
2) Then we create a service using Angular-CLI
ng g s metamask
in this service, we start by creating a basic getter for our wallet info which returns wallet connection status and its address.

It may seem simple as you may have some data in tables (hello, MySQL) and you want them on a web page (hi, <table>). But you start joining data from other tables and you end up displaying a tree in a table. How? You never know how to do it until you try to use that. UX!

But if you have tree-data, tree-database (hello, Mongo), and tree components on website, you still need tables to present the data of similar structure. It's all 2D and are brains are trained to get information presented as combination of 2 axes. Hello, tables!

Après des mois de travail à distance imposé, notre bureau #Montpellier se réinvente pour accompagner notre transition sur le modèle d'Hybrid Workplace : nouveaux espaces de collaboration et de visio-conf, nouveaux espaces de travail #flexoffice et nouvelle déco ! 🔽 thread !
Le télétravail existe depuis toujours à Hawk, mais force est de constater que durant ces deux dernières années il a pris une part prépondérante dans notre quotidien. Notre organisation future sera un modèle hybride où télétravail, présentiel et remote cohabiteront harmonieusement
Le flex office, pour ou contre ? Chez Hawk la réponse a été quasi-unanime : POUR 👍 ! Parfait pour booster le foisonnement d'idées et favoriser l'émergence de solutions innovantes.
Et pour soutenir ce changement, quoi de mieux que des nouveaux espaces de travail modernisés ?
