--description--

A record consists of attributes that describe an entity. Each attribute has a name and a value. For example, a person can have an attribute age with a value of 25. An important operation on a list of records is to find a record with a particular attribute value.

--instructions--

Write a function that takes a string as a parameter. The function should return the index of the item in list for which the value of the name attribute matches the given string.

--hints--

searchCity should be a function.

assert(typeof searchCity === 'function');

searchCity("Dar Es Salaam") should return a number.

assert(typeof searchCity('Dar Es Salaam') === 'number');

searchCity("Dar Es Salaam") should return 6.

assert.equal(searchCity('Dar Es Salaam'), 6);

searchCity("Casablanca") should return 9.

assert.equal(searchCity('Casablanca'), 9);

searchCity("Cairo") should return 1.

assert.equal(searchCity('Cairo'), 1);

searchCity("Mogadishu") should return 4.

assert.equal(searchCity('Mogadishu'), 4);

searchCity("Lagos") should return 0.

assert.equal(searchCity('Lagos'), 0);

function searchCity(name) {
  return list.findIndex(item => item.name === name);
}

const list = [
