Array 'fill' method in Javascript (Array.prototype.fill)

Показать описание

The 'fill' method allows you to fill an array with a single value that you pass in. This is clearly useful if you wanted to change the value of all elements in an array at once.

With objects however, only one object gets created and each element instead has a reference to that object. Instead you'll want to use the 'map' method to achieve the same effect - which we also cover in this video.

Had a problem using the .fill() array method for a advanced software design course I am taking and this perfectly explains why .fill() wasn't the right method to use! Thank you!!
