Before we discuss how WebAssembly is used as a compilation target across different language ecosystems, we can explore it online without requiring any kind of setup on our machine. Some tools that can be used to do this are as follows:

• WebAssembly Studio: The folks at Mozilla have created a really handy tool to try out WebAssembly in a quick way, and it's hosted at https://webassembly.studio. Using this tool, we can experiment and prototype ideas in WebAssembly really quickly.
• Wasm Fiddle: This is another handy tool for trying out wasm code online, and can be found at https://wasdk.github.io/WasmFiddle/.

There are other tools online and community resources for you to explore, all of which you can find at https://github.com/mbasso/awesome-wasm.
