JavaScript Code Can not Load

As a programming student, I have a project as my homework from my teacher, My homework is to make a simple company profile website.

I use JavaScript Code to make a my website layout better and responsive but all my script can not be laoded in a browser such as Google Chrome, Mozilla and many others. Suddenly, all systems in my laptop stop on the other hands I can move all such as cursor mouse and many others. Actually, I set the JavaScript for browser Enable. Unfortunately, result is unexpected.

What Should I do to solve this ?
