Tip: Try to remove dependencies of jQuery in your projects as much as you can - VanillaJS.

document.firstElementChild returns tag then the classList attribute returns all classes added to it.

if(document.firstElementChild.classList.contains("your-class")){
    //  has 'your-class'
} else {
    //  doesn't have 'your-class'
}
