| 6 |
|
|---|
| 7 | - Everything is in JavaScript.
|

| 8 | - No platform-dependent blocks.
|

| 9 | - Some things like crc32 rewritten to keep size small and make JIT
|

|

| 11 | - Some code is different due missed features in JS (macros, pointers,
|
|---|
| 12 | structures, header files)
|

| 13 | - Specific API methods are not implemented (see notes in root readme)
