Tell us what’s happening:
I can’t access the property ‘prop’ value by contacts[i].prop but contacts[i][prop] works fine. Why is this happening? As far as i know, ‘’ can be equivalently used in place of ‘.’ for accessing the objects or arrays.
Your code so far
//Setup
var contacts = [
{
"firstName": "Akira",
"lastName": "Laine",
"number": "0543236543",
"likes": ["Pizza", "Coding", "Brownie Points"]
},
{
"firstName": "Harry",
"lastName": "Potter",
"number": "0994372684",
"likes": ["Hogwarts", "Magic", "Hagrid"]
},
{
"firstName": "Sherlock",
"lastName": "Holmes",
"number": "0487345643",
"likes": ["Intriguing Cases", "Violin"]
},
{
"firstName": "Kristian",
"lastName": "Vos",
"number": "unknown",
"likes": ["Javascript", "Gaming", "Foxes"]
}
];
function lookUpProfile(firstName, prop)
{
// Only change code below this line
var flag1=0, flag2=0;
var p;
for(var i=0;i<contacts.length;i++)
{
if(contacts[i].firstName===firstName)
{
flag1=1;
if(contacts[i].hasOwnProperty(prop))
{
flag2=1;
p=contacts[i][prop];
}
}
}
if(flag2===1)
{
return p;
}
else if(flag1===1)
{
return "No such property";
}
else
{
return "No such contact";
}
// Only change code above this line
}
// Change these values to test your function
lookUpProfile("Kristian", "lastName");
