I sometimes like to work quickly, so I set a macro in my editor to always add a semicolon after an end curly-brace, even when not necessarily needed. For example: 

var test=function(){
    //I realize the semicolon after the curly-brace below is required
};

function test(){
    //But is it safe to have on where it isn't required, like below?
};

As in, will it create errors, slow down the site, or create compatibility issues? I will remove these additional semicolons when I am finished developing the product, but for now, is it OK?

Note that there are cases where adding a semicolon after an ending curly bracket can cause issues, e.g.:

let data = {
  item1: [],
  item2: {}; // This semicolon is a syntax error
};

On a program level, it makes no difference to have this:

function() {

};

Or this:

function() {

}

I do recommend that you pick one way to do it and stick with it for the purpose of consistency.

You should also read through this post: Do you recommend using semicolons after every statement in JavaScript? A lot of good points on this subject are made there.
