Can we declare a var Stable?

This might help you, you don’t need to change the Array, just use the Buffer when using the append method.

What's the good way to add a new item in array?

ie. if I have the following: return Array.append<Project>(theProjectsNew, [newProject]); which appends a new object “newProject” to an array called “theProjectsNew” and replace it with: let theProjectsBuffer : Buffer.Buffer = Buffer.Buffer(theProjectsNew.size()); for (x in theProjectsNew.vals()) { theProjectsBuffer.add(x); }; theProjectsBuffer.add(newProject); return theProjectsBuffer.toArray(); the programatic results are the same … and the warning goes away … is this a valid way …
