I agree. I love ES6 in fact. The fat arrows really rock. I like how I can use them together with promises to write a concise code like create_project(prj_name).then(project=>addTeam(project, team_name)).then(team=>addMember(team,name)) The main point of the article was in that using new JS features blindly may cause the significant problems, not with readability, but with the script size and the running time of the code after it’s transplied to ES5.
