WebAssembly WASM

Scott C. Krause | Friday, Aug 5, 2022



Frequently Asked Interview Questions


Which languages does WebAssembly support?

.Net, AssemblyScript, C, C#, C++, Clean, Cyber, COBOL, F#, Forth, Go, Grain, Lobster, Lua, Motoko, Nelua, Never, Python, Rust, Rego, TypeScript, and Zig

Can a WASM program access elements on the web page?

WebAssembly cannot directly access the DOM. It calls JavaScript, passing in integer and floating point primitive data types. Thus, to access any Web API, WebAssembly needs to call out to JavaScript, which then makes the Web API call.

Can I author WASM in JavaScript or TypeScript?

Yes, AssemblyScript is like TypeScript (strict variant). Allowing web developers to keep using TypeScript-compatible tooling that they are already comfortable with.

Flickity Carousel A11y Observer
Flickity Carousel A11y Observer
Observe and listen for changes in the Flickity carousel
// Desc: This patch will observe and listen for changes in the Flickity carousel, and when triggered will remove aria-hidden from the carousel child elements. It will observe every carousel instance that exists on the page. This logic utilizes the mutation observer to watch all carousels for changes. The changes may be user initiated or actuated via autoplay configuration.
// Usage: flickPatch = new FlickPatch( document, ".flickity-slider" ); flickPatch.init();

The Neodigm 55 Heatmap component captures the amount of time that each card is visible to an end user on a laptop or mobile device.

The summation of card activity is then packaged into the analytics data layer to be consumed by Adobe Analytics or Google Analytics. Activity that occurs while offline will be updated upon reconnection to the network if the app has not been closed.

The Neodigm 55 Heatmap component utilized the Intersection Observer pattern to track when and for how long block elements (cards) are visible in the user agent viewport.

The component is configured to only report if a card is visible for greater than 3 seconds. This threshold is configurable. There are some edge cases wherein data may lose fidelity. For example if the user opens another tab or abruptly closes the browser while a card is within the viewport.

The component captures the existence of cards within the browser's viewport, however the application may partially obstruct the viewport with an overlaying menu. Meaning that the Heatmap may report that a particular card is in view a few microseconds before it is actually visible. This discrepancy is so small that it is not statistically significant.

The data layer entries that the heatmaps create are additive, meaning that there may be more than one for a single component. This is because the end user viewed a particular card component, exited the card, then reentered the card.
