WebAssembly Tutorial - 1 - Installation and Hello World

This is the introduction video to WebAssembly and emscripten. We introduce WebAssembly as an Assembly-type language that allows web browsers to harness the raw power of the CPU, not limited by layers of abstraction between javascript and the CPU. The first part goes over the installation of emscripten, the platform used to compile code into WebAssembly. Then, we write a simple "Hello, world!" example in C and compile it to WebAssembly and see its output in several different ways using JavaScript and HTML.

Thank you!! Been waiting for something like this for years. Talk about about slow WA adoption.

At 3:40, you say I have type "emsdk activate" in cmd, it gives me the message:
No tools/SDKs specified to activate! Usage:
emsdk activate tool/sdk1 [tool/sdk2] [...]
Could you tell me how to fix this?
Thanks in advance!

Edit: I've now typed "emdsk activate latest" and it seems to work

I tried the same based on the website, but when I type emsdk with any command after it, it gives no response and creates an indefinite amount of python.exe processes eventually eating up all memory.
