For interactivity and responsiveness.
It makes webpages dynamic and not static

Answer 5

it depends, if your script is going to be used for one specific page, use the <script></script> method

keeping script in same html file is better , as it would take one less http request , so 2 is better,

but when files get very big and complicated it's better to put separate JavaScript file and use src
