1. __Legacy__: [WebAssembly][wasm] is unlikely to replace JavaScript, but, instead, serve a complementary role. JavaScript has a long and decorated history as part of the web platform. Relegating JavaScript to the dust bin would entail breaking the Web, an outcome which has been and will continue to be untenable, thus securing JavaScript's privileged status.

1. __Scripting__: [WebAssembly][wasm] does __not__ eliminate the need for a scripting language. Even if lower level, performance critical math implementations are [WebAssembly][wasm] compiled C/C++ libraries, a dynamic, loosely typed, interpreted scripting language is still necessary. The iteration cycle when using compiled languages is simply too long when compared to dynamic languages, particularly within the context of interactive analysis. Accordingly, functionality is, and will continue to be, necessary in JavaScript, a scripting language to which, given the size and energy of its community, every other scripting language pales in comparison.
