What is the best way to transfer one form data to another form in Angular 2 or generic web devlopment?

I would like to know -

• What are the different techniques to transfer one form data into another form in Angular 2 or in general web development?
• Pros/Cons of each technique and when to use what

I have come to know the following different processes -

• Using API (i.e. through query params). Example - https://www.jotform.com/help/351-How-to-Automatically-Pass-Form-Data-to-Another-Form
• Using HTML5 local storage or session storage

Transfer data from one HTML file to another lists down the options I have mentioned above.

I am a newbie in web development, so my knowledge is limited, but I am willing to handle complex process if that is more efficient than others.
