Remove element from array of objects

Helper for removing objects using computed nested key names.

Before:

const users = [...this.state.users];
const userIndex = users.length
  ? users.findIndex(user => user.name && user.name.first === 'John')
  : -1;
userIndex > -1 && users.splice(userIndex, 1);
this.setState({ users });

After:

const users = removeFromArray(this.state.users, 'name.first', 'John');
this.setState({ users });

• Works for unlimited keys chain length (accepts string, can be single key name or names seperated by dots)
• If element wasn't found returns original array
• If element was found, returns new array - immutable function
