Quick addition. In some IDE like Visual Code, putting Curly Braces will actually create a visual block with a 'drop-down' arrow, allowing you to completely hide a portion of code with just a click. It helps with code organization. I'm using it when creating HTML element with a lot of CSS. Since it does not affect code execution, this is very useful.
