[ES6] Object.assign (with defaults value object)

function Spinner (target, options = {}) {  = {    "Please Wait",    5,     ". is-spinning"  };   = Object.assign (    {},    defaults,    options  );   if (Settings.spinningspeed!== defaults.spinningspeed) {    = _addspeedclass (target);  }  _renderspinner (target, settings);}

• Best Pratices to write defaults as a objects, much clean and reuseable.
• Write a empty object {} to the object.assign is recommened, it avoid defaults been mutated.
• If block, you see we might still use default value, so it's important to keep the origin defautls value.

Example2:

function Spinner (target, options = {}) {  = {    "Please Wait",    5,     ". is-spinning"  };   = object.assign ({}, defaults, options);  Console.log (' Message: ${settings.message} ');  Console.log (' Spinningspeed: ${settings.spinningspeed} ');  Console.log (' CssClass: ${settings.cssclass} ');} Spinner (Targetelement, {  ". is-fast-spinning",   8 });
