 1. __Bundling__: page load times are, and will continue to be, important, especially for business critical applications. The JavaScript community has invested considerable time and effort to both developing tooling and improving the web platform to bundle only code which is actually used and needed. Libraries written in other languages (e.g., [NumPy][numpy]) are not as amenable to modular bundles. Lack of modularity combined with significant size renders many non-JavaScript libraries impractical for web applications.
 1. __Timescale__: [WebAssembly][wasm] is not likely to be ubiquitous anytime soon (as of 2016) and a need exists now for numeric computation libraries which work on the Web.
 1. __Monoglot__: developers will still build JavaScript applications and most will, all things being equal, want to use a library written in the same idiom. Using a single language stack reduces cognitive overhead and simplifies application development.
-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.
