This is something I have observed about every language&#x2F;framework front end combo I have ever used and I have done it long enough to go all the way back to Qt 3 and even before. There is no terse way to describe a UI. Period. C++ or Java I understand they are typed languages with an avowed aim of giving the programmer fine grained control over the program. Objective C may have become popular more recently but it too is an older typed language. The unbrevity of JavaScript is inexcusable and it extends to every UI framework it offers. Tooling is no way to try and ease the problem.
