State of JavaScript 2024

Recursos

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”.

Pontos Problemáticos das APIs do Navegador

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.
