We are potentially removing the complexity at all ends. Right now the chain is: Developer writes code in something like Typescript that then is translated to Javascript and then is downloaded by the browser (huge downloads compared to binary code). The browser then needs to parse that huge amount of javascript code to compile it into a bytecode that can then be JIT executed or interpreted. With webassembly it would be as follows: Developer writes code in the language of his/her choice, that then is compiled to a small bytecode. This bytecode is downloaded by the browser and then it is JIT executed or interpreted. It is simpler, more flexible, and potentially faster.
