The first is a DOM ready handler function used in jQuery (a JavaScript library). It is executed when the DOM is fully loaded. Whereas, the second is a simply defined function with name myFunc.
You can read more about JavaScript functions in MDN: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Function.

They are totally different uses of function.
The first on calls function $() with parameter function() {}.
The second defines function myFunc.

$() is a shorthand for jQuery's document.ready syntax: Documentation
Code inside a $() will run when the dom has loaded enough to be accessed/manipulated.
The second example is just a normal function declaration and creates a function named myFunc that can be called with syntax myFunc() later.
