Deleting a Team

The delete process is similar to the update. First, we need to retrieve a valid index from the teams array and then remove it from there. Open the teams-api.js file and apply the following changes:

...api  .route('/teams/:id')  .get((req, res) => {     ...  })  .put((req, res) => {     ...  })  .delete((req, res) => {    const id = req.params.id    const index = lookupTeam(id)    const team = teams[index]    if (index !== -1) {      teams.splice(index, 1)      return res.send(team)    }    return res.status(404).send('team not found')  })...

So we define a .delete route and look up for a team by passing the id param. If a valid index is returned, we save the team instance in the team variable. Next, we delete the element from the array using the splice(index, 1) expression. ...
