How to include JS files in the WORDPRESS index file?

Question

JavaScript

I need to connect this directly in the theme index file, but it gives an error in the console that this very yepnope is not defined, how can I fix this?

yepnope({
  test : Modernizr.csstransforms,
  yep: ['ЗДЕСЬ ПУТЬ/lib/turn.js'],
  nope: ['ЗДЕСЬ ПУТЬ/lib/turn.html4.min.js'],
  both: ['ЗДЕСЬ ПУТЬ/css/basic.css'],
  complete: loadApp
});
