Iam finishing with app iam developing, but i would like it to be a little faster in loading time and even in reaction. Make it feel more smooth. Are there any best practises for optimizing ionic app? Maybe some things in code that should be avoided(for example what about foreach on big arrays and so on), or are there any other tricks, beside building apps with --prod flag?
And maybe another question, are there any tools to analyze apps performance and which methods or components are problem?
