Svelte with Test Driven Development - keyed each

This is taken from my course at udemy. Here is the discount link bafoly.com/?co...
With {#each} functionality of svelte, we can use same component in a loop. This each functionality is reuising components. And we can use unique id's we can rely on to make sure this each functionality to reuse components only if the id is not changed. So in this one I'm demonstrating a potential problem and how to fix it with keyed each.
