In the POST operation the Genre ID is being auto-generated based with this line of code
id: genres.length + 1

Suppose Intially if the genres list is like below,
{id: 1, name: 'Genre1'},
{ id: 2, name: 'Genre2'},
{ id: 3, name: 'Genre3'}

And now if remove the genre with the id:2 then the genre list will be like
{id: 1, name: 'Genre1'},
{ id: 3, name: 'Genre3'}

And If we now add a now course then the ID is being duplicated like
{id: 1, name: 'Genre1'},
{ id: 3, name: 'Genre3'},
{ id: 3, name: 'Genre4'}
