State of JavaScript 2024

Funcționalități

While they aren't seeing wide usage just yet, JavaScript's new Set and Object features will make it less necessary to rely on third-party utility libraries.

Also, whenever available we now display each feature's Baseline status: green for “widely available”, blue for “newly available”, and white for “limited availability”.

Puncte slabe ale API-urilor de browser

Unsurprisingly, poor browser support was the top obstacle regarding browsers and their APIs. Safari was also highlighted as a common pain point, and so was the overall lack of documentation about browser features.
