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
