import deleteIn from '@mzvonar/deletein';
  
const context = {
    user: {
        profile: {
            gender: 'female'
        },
        ids: [1, 2, 3]
    }
};
  
const newContext = deleteIn(context, ['user', 'profile', 'gender']);

returns:

    {
        user: {
            profile: {}
        }
    }

const newContext = deleteIn(context, ['user', 'ids', 1]);

returns:

    {
        user: {
            profile: {
                gender: 'female',
                ids: [1, 3]
            }
        }
    }

mutableDeleteIn

If you need you can import mutableDeleteIn, which is exactly the same as deleteIn, but mutates the original context object without creating copy.
