This freeCodeCamp project exposed me to more DOM manipulation, objects and nested objs, and switch statements. New concepts I got (re)introduced to include the Object.freeze() method preventing any changes to an obj, the .map() method which returns an altered copy of an array, default parameters and thank you mucho to the creators of obj destructuring.
All the data was stored into one main object. Object destructuring was used to access object properties. Those prop values were then inserted into a player card via the call back function that is passed into the .map() method that was called on the players array property within the main object. An event listener was called on the select element via the change event, the value of that event was passed in as the condition for a switch statement that filtered then displayed player cards that had data that matched the given condition.
