I used app in list and it is ok.
Now I have a the question. I don't know what is no javaScript and what is react.

I do not know what the difference is in the no javaScript and react and Knockout
Can anybody tell me what is difference?

Can I use javeScript in no javaScript? I prefer to use JavaScript because I know this language and do not want to enter a new language like React

Hi @daryush salahshur ,
React and Knockout are both JavaScript library for building user interfaces.
I would recommend React since React makes it painless to create interactive UIs.
React is extremely intuitive to work with and provides interactivity to the layout of any UI. Plus, it enables fast and quality assured application development that in turn saves tome for both - clients and developers.
A strong blend of JavaScript and HTML syntax is always used, which automatically simplifies the entire process of writing code for the planned project. The JS library consists several functions including one that converts the HTML components into required functions and transforms the entire project so that it is easy to understand.

JavaScript frameworks are nothing but an abstraction layer on top of plain JavaScript that eases your web development experience. React and Knockout are some of these frameworks. It is not mandatory to use JavaScript framework for development using SPFx. Selecting 'No JavaScript Framework' at the time of project creation does not add extra libraries for React or Knockout in your project. You can still use plain JavaScirpt for development in SPFx when 'No JavaScript Framework' is selected.
