Description:
Given: an array containing hashes of names
Return: a string formatted as a list of names separated by commas except for the last two names, which should be separated by an ampersand.
Example:
list([ {name: 'Bart'}, {name: 'Lisa'}, {name: 'Maggie'} ])
// returns 'Bart, Lisa & Maggie'
list([ {name: 'Bart'}, {name: 'Lisa'} ])
// returns 'Bart & Lisa'
list([ {name: 'Bart'} ])
// returns 'Bart'
list([])
// returns ''
Note: all the hashes are pre-validated and will only contain A-Z, a-z, '-' and '.'.
function list(names){
//your code here
let res = '';
for (let i = 0; i < names.length; i++) {
if (i === names.length -2) {
res += names[i].name + ' & ' + names[i+1].name
break;
}
res += names[i].name + ', '
}
return names.length === 1 ? names[0].name : res
}
