stp2y0 CommentsNewscoding, community, database, development, engineering, inclusive, kawsarkabir, MongoDB, software, webdev

To delete documents in MongoDB, you can use the deleteOne() or deleteMany() methods. These methods allow you to remove one or multiple documents, respectively. Here’s an example of using the deleteOne() method to remove a single document: db.collection.deleteOne({ _id: ObjectId("your_document_id_here") }); Enter fullscreen mode Exit fullscreen mode If you want to delete all documents, you can use the deleteMany() method: db.collection.deleteMany({}); Enter fullscreen mode Exit fullscreen mode Additionally, you can delete all documents that match a specific condition: db.collection.deleteMany({ your_query_here }); Enter fullscreen mode Exit fullscreen mode To delete an entire collection, use the drop() method: db.collection.drop(); Enter fullscreen mode…

An accordion component is a component that has one or more expandable sections within it. It’s pretty common to have the need for this type of thing when building apps in Angular. And, it’s not the most difficult thing to do even if you’re creating your own from scratch but the CDK makes it really simple. In this example I’ll show you just how easy it is. And after we create the accordion using the CDK, we’ll even make it accessible with some ARIA. Alright, let’s get to it! The Demo Application For the example we’ll be working with in…

Pseudocode/Python Project

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, python, software, webdev

Hey All. I am writing a program that uses conditionals as well as a while loop. I am running into problems with the while loop. The loop is set to run if the user doesn't enter 'yes' or 'no' when asked whether they would like to make a payment. No matter where I try to place the loop it seems to get stuck if I enter anything other than 'yes' or 'no' then enter either 'yes' or 'no' after the loop. It seems that if I try to catch someone not entering either of the two acceptable entries the program…

GIF to JPG: Transitioning Between Image Formats

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software

What Are the Differences Between GIF and JPG? GIF (Graphics Interchange Format) and JPG (or JPEG - Joint Photographic Experts Group) are two of the most widely used image formats, each serving different purposes and possessing distinct characteristics. GIF - Compression: GIF uses lossless compression, which means no image data is lost, preserving the quality. However, it is limited to a palette of 256 colors, which can restrict its use for detailed images.- Animation: GIF supports animations, allowing multiple frames within a single file, making it ideal for simple animated graphics.- Transparency: GIF supports binary transparency, meaning a pixel can…

Seamless State Management using Async Iterators

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, node, software, webdev

In my recent post about AI-UI, I touched on why I developed the library. I wanted declarative markup I wanted type-safe component encapsulation, with composition & inheritance I wanted a small, fast client-side solution with no complex build process (or any build process!) ...but most importantly... I didn't want to learn a whole new API just to manipulate data I already have in my app In my single page apps, I've got remote APIs and endpoints that supply data. Sure, I might want to do a bit of arithmetic, sorting, formatting, but basically, I want to say to the UI:…
