Similar to emscripten-core#27425 but applied to the whole JS library - Replace explicit zero checks (`=== 0`, `!== 0`) with implicit truthy/falsy checks (`!x`, `x`). - Replace `.length === 0` checks with `!arr.length`. - Simplify null/undefined/zero check in `src/lib/libccall.js` to `if (str)`. - Use `for (var byte of data)` loop in `src/lib/libbrowser.js`.
