What are the advantages of using iframe and switching display to open a new tab page in the system rather than in the browser? Experienced progress

background:
stated this problem last time. I don"t know if you have ever done software like this:

Open a new tab,
react, for the system inside the system at that time there are two options:

  • 1 is the tab component that uses antd
  • 2 has seen several similar systems, all using iframe (but they are not using react)

now, after thousands of difficulties and obstacles, it has been implemented in iframe, but after I have done it, I have a few questions that I think I do not understand deeply. Now I would like to discuss

with you.
  • 1 where is it that I use iframe?
    make full use of the current web page resources and make great use of the memory allocated by the browser? If so, the tab component of antd claims to have done some encapsulation, not simply switching display, back and forth, so could I have directly used the tab component of antd instead of iframe?? in the first place?

Don't use iframe if you can. If
must be used, react has iframe components, please use components, do not directly use < iframe / >
antd tab is your best choice.

iframe and display have no advantages.

just use a div .
each time you switch tab , just load the component corresponding to tab .
for example: 

  
 compares using antd's tabs and using multiple iframe in the google browser. 
 preliminary conclusion: open multiple tab pages, both take up browser memory for the currently open tab page, the currently open tab page is very large, both will render crashed, iframe does not have any obvious advantage.
