Tell us what’s happening:
I am trying to solve the challenge Basic JavaScript: Profile Lookup but everytime i run it I get the output ‘’. The loop runs OK and even goes inside the first if condition :
if (name === contacts[i].firstName && contacts[i].hasOwnProperty(prop))
and checks for the condition and even return the value ** “[“Intriguing Cases”,“Violin”]” ** in console.log. But somehow it doesn’t passes the test with the same condition.
Any Idea How could that happen?
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(name, prop){
// Only change code below this line
console.log(contacts.length)
var i = 0
var returnValue = "";
while ( i < 4 ) {
console.log("i inside for loop " + i)
// console.log("Name before if: " + name)
// console.log("Property before if: " + prop)
// console.log("Value of the Property before if loop: " + JSON.stringify(contacts[3].lastName) )
console.log("name before if loop " + name)
console.log("contacts[i] before if loop" + JSON.stringify(contacts[i]) )
console.log("contacts[i].firstname before if loop " + JSON.stringify(contacts[i].firstName))
console.log("contacts[i].hasOwnProperty(prop) before if loop " + contacts[i].hasOwnProperty(prop))
console.log(" 'i' before if loop " + i)
if (name === contacts[i].firstName && contacts[i].hasOwnProperty(prop)) {
console.log("name inside if loop " + name)
console.log("contacts[i] inside if loop" + JSON.stringify(contacts[i]) )
console.log("contacts[i].firstname inside if loop " + JSON.stringify(contacts[i].firstName))
console.log("contacts[i].hasOwnProperty(prop) inside if loop " + contacts[i].hasOwnProperty(prop))
console.log(" 'i' inside if loop " + i)
// return contacts[i].prop
// console.log("i inside if loop" + i)
// console.log(" name inside if loop " + JSON.stringify( contacts[i].firstName ))
console.log("contacts[i] inside if loop " + JSON.stringify(contacts[i]))
console.log("prop inside if loop " + prop)
var jsonValue = (contacts[i][prop]);
returnValue = JSON.stringify(jsonValue)
console.log("returnValue " + returnValue)
}
else if ( name != contacts[i].firstName ) {
returnValue = "No Such contact"
}
else if (prop != contacts[i].hasOwnProperty(prop)) {
returnValue = "No such property"
}
i++;
console.log("i at the end of for loop " + i)
}
return returnValue
// Only change code above this line
}
// Change these values to test your function
lookUpProfile("Sherlock", "likes");
