TypeScript
Regular TypeScript
TypeScript code is executed via a Jupyter kernel. Markdown Exec will attempt to use any kernel that lists TypeScript as a supported language, however Markdown Exec is tested using the Jupyter kernel provided by the Deno project. See Deno's installation instructions and Jupyter kernel docs for more information.
Output capturing
Outputs are captured just as they are in jupyter notebooks.
```typescript exec="1"
console.log("**Hello world!**");
```
Type checking
TypeScript code blocks will be type checked using Deno's type checker.
```typescript exec="yes" returncode="1"
const x: string = 1;
```
TypeScript REPL console code
Code blocks syntax-highlighted with the tscon identifier are also supported.
These code blocks will be pre-processed to keep only the lines
starting with > , and the chevron (prompt) will be removed from these lines,
so we can execute them. Continuation lines starting with ... are also supported
(and the ellipses will be removed as well).
```tscon exec="1" source="console"
--8<-- "usage/source.tscon"
```
It also means that multiple blocks of instructions will be concatenated, as well as their output:
```tscon exec="1" source="console"
--8<-- "usage/multiple.tscon"
```
