Way to use

It's pretty easy to use! As you see, there is a displayer on top and a keyboard on bottom.

There are 2 modes for displayer: code mode and output mode. You can switch it by clicking it.

Especially, there is a pointer on the displayer, you can move by specific keys in keyboard (see below) it to view different part of the display code or output: just like rolling your eyeboll!

By the way, the way to output is a bit different: you need to use the built-in function echo(data, flags = echoOps.W) to output and clearEcho() to clear it. What's more, there is a function to accept user's input: input((data) => { ... }).

For more features and details, just see the next part!

Built-in APIs

There is the list of built-in APIs in the JStudio runtime environment:

  • echo(data, flags = echoOps.W): display the data on the displayer (values of enum echoOps: W (stands for 'add Wrap'), P (stands for 'with Prototype'), L (stands for 'support Long strings'), F (stands for 'support Functions'))
  • clearEcho(): clear the displayer
  • input((data) => { ... }): accept the data which user inputs
  • cn(pinyin): query the pinyin table according to the specific pinyin
