Trying to figure out the difference in JS between these ways of doing WP Gutenberg blocks

blocksVariableDefinitions.js

// I've seen code for building WP blocks with JS like this

( function( blocks, editor, i18n, element) {
    var el = element.createElement;
    var __ = i18n.__;
    var RichText = editor.RichText;
  // do block things
  }(
    window.wp.blocks,
    window.wp.editor,
    window.wp.i18n,
    window.wp.element
    
) );

// and like this

( function() {
    const blocks = window.wp.blocks;
    const editor = window.wp.editor;
    const i18n = window.wp.i18n;
    const el = window.wp.element.createElement;
    const RichText = editor.RichText;
  // do block things
  }(
) );

//just a difference of how the same objects are passed, or is there a scope subtlety I'm missing?
