Targeting ES6 in tsconfig.json Fixes kann den Namen nicht finden

Ich gehe durch ein Tutorial auf AngularJS. Der Code kann bei https://github.com/planetoftheweb/learnangular/tree/02_01e
gefunden werden Ich verwende genau diesen Code. Als ich npm Start laufen, ich diesen Fehler:Targeting ES6 in tsconfig.json Fixes kann den Namen nicht finden

Wenn ich das Ziel in tsconfig.json Form ES5 ändern es6, funktioniert alles. Ich habe an anderen Orten gelesen, dass Targeting ES5 grundsätzlich Standard ist und wenn Sie ES6 als Ziel haben, besteht die Gefahr, ältere Browser nicht zu unterstützen. Ist das immer noch wahr? Wenn es ist schlechte Praxis, was ist eine bessere Lösung?

ES6 wird von den meisten Browsern noch nicht wie IE unterstützt, wenn Sie auf ES6 zielen, dann brauchen Sie einen Transpiler wie Babel oder Traceur js, um den Code zu transpilieren, damit der Browser es verstehen kann – Niladri

Es gibt eine issue für genau dies auf dem GitHub-Repository. Einer der Kommentare auf es gibt eine Lösung, die für ein paar Leute gearbeitet zu haben scheint:

...solved it by adding this line to my tsconfig.json file "lib" : ["es2015", "es2015.iterable", "dom"]

wie Sie vorgeschlagen, Targeting ES5 gibt bessere Browser-Unterstützung. Sobald Sie ES6 als Ziel haben, benötigen Sie einen Browser, der ES6 unterstützt, was je nach Zielgruppe ein Problem darstellt. Persönlich würde ich ES5 für die höhere Kompatibilität zielen.
