The syntax is pleasant, familiar, and powerful, and the all-in-one ecosystem makes it a breeze to build and release rapidly.
What do you dislike?
Not being in the spotlight means that the number of video tutorials and books in print are less than those of fad languages, libraries, and toolkits.
Recommendations to others considering the product
Build something simple in Dart as a test, then try to do the same thing in JS, TypeScript, or any other alt-lang. You'll instantly see the contrast.
What business problems are you solving with the product? What benefits have you realized?
Dart lets you relax into well-organized files, folders, and libraries in one place, and then pop out a single tree-shaken JS file at the end! This is wonderful if you have every been frustrated with the need to gather and configure the myriad tools and packages in the JS ecosystem and wire them up together. You basically get the equivalent of the _next_ version of all those tools in one, as Dart leads the way and the rest of the world follows.
