One cool thing that block-based coding allows for is a more tangible coding experience for young learners. Not only on-screen, but also something kids can hold in their hands with something likeScratch Cards; which is a set of cards that offers a physical, visual representation of different ...
Using block lettering in coding can be a great way to improve code readability and performance, but it must be used effectively. For example, when naming variables, constants, or functions, it is recommended that only the first letter of each word is capitalized. This will allow for improved...
What is a block? A block refers to a fundamental concept in various technological and computing contexts. It involves breaking down data or tasks into smaller, manageable units called "blocks." These blocks are then processed, transmitted, or stored as needed. ...
Blockchain is still plagued by a number of challenges, with some of the main issues being transaction bottlenecks, scalability limits and high levels of energy consumption. Can blockchain transactions be reversed? No, blockchain transactions can’t be altered after being initiated. This is due to...
This JavaScript code defines a function called "greet" that takes a name as input and prints a personalized greeting message to the console. These are just basic examples, but they showcase the fundamental structure of code. As you progress in your coding journey, you'll create more complex ...
In apublic blockchain network, the first node to credibly prove the legitimacy of a transaction receives an economic incentive. This process is called “mining.” Here’s a theoretical example to help illustrate how blockchain works. Imagine that someone is looking to buy a concert ticket on ...

Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network.
found JScript's closures particularly useful is in breaking up long calculations that have a lot of state on the stack. You can't pump messages manually in the browser but you can window.setTimeout(function() { /* next block of code */ }, 0) which permits you progress bar to repaint...
The Bitcoin blockchain collects transaction information and enters it into a 4MB file called ablock(different blockchains have different size blocks). Once the block is full, the block data is run through a cryptographic hash function, which creates a hexadecimal number called theblock headerhash...
