JavaScript also uses block scope. When we say block, we are referring to a code block. A code block is contained within curly braces. Information is encapsulated to the curly braces within the block of code. Here is an example…
If( 1 === 1) {
let name = ‘Bongo’;
}
console.log(name);Since the variable name is within the curly braces, or block of code, it is not available outside of those curly braces. The log statement would return undefined.
Happy Coding!

The Device Posture API helps web apps adapt to foldable devices by detecting whether a screen is continuous or folded and reacting to posture changes.
Device Orientation Events let web apps read a phone’s real-world tilt and rotation. This demo streams alpha/beta/gamma values, smooths jitter, and maps motion to a 3D box—while handling HTTPS requirements and iOS permission prompts.
