- https://caniuse.com - per-feature tables of support, e.g. to see which engines support modern cryptography functions: https://caniuse.com/#feat=cryptography.
- https://kangax.github.io/compat-table - a table with language features and engines that support those or don't support.
All these resources are useful in real-life development, as they contain valuable information about language details, their support, etc.
