 This has the advantage of not requiring an internet connection in order to code the micro:bit. Once the browser editor at [makecode.microbit.org](https://makecode.microbit.org) loads, it is cached on your computer.
 
-The MakeCode editors contain a copy of the micro:bit runtime [the DAL/CODAL]({{ "/software/runtime/" | relative_url }}) which the blocks and javascript APIs reference.
+The MakeCode editors contain a copy of the micro:bit runtime [the DAL/CODAL]({{ "/software/runtime/" | relative_url }}) which the blocks and JavaScript APIs reference.
 
 When you press **Download** the compiler converts the code into a machine readable [hex file format]({{ "/software/hex-format" | relative_url }}).
 
 When this .hex file is flashed onto the MICROBIT drive, the KL26/7 interface processor on the micro:bit copies it into the flash memory inside the nRF application processor and the code runs.
 
 ## Other Features
 
-MakeCode supports two-way conversion of code, so you can write code as blocks and see what the generated code looks like in Javascript/MakeCode Python. You can also write Javascript/MakeCode Python code, and if possible, MakeCode will convert this back into blocks automatically.

 MakeCode also allows you to [write your own block types](https://makecode.com/extensions) and [publish them as Extensions](https://makecode.microbit.org/extensions).
 
 ## Offline
 
- An [offline version of the MakeCode editor](https://makecode.microbit.org/offline) is available for use in situations where there is limited or no internet connectivity.
