Question

can someone correct me where am i wrong in writing this code.
to find needle in haystack using for loop and return
found the needle in position x. x being the index number.

var haystack =[“hay”, “needle”, “ rabbit”, “hat”];
for (i=o;i<=haystack.length;i++){
console.log(haystack[i]);
}
function findNeedle(haystack){
return “found needle at position” haystack[i].indexOf (“needle”);
}
findNeedle(haystack);

Answer 1

1. you forgot to put the keyword var inside forloop
2. you are assigning i=o instead of i=0 (i.e.zero)
3. you are running the loop 5 times instead of 4
4. return statement should contain + operator
5. haystack.indexOf("needle") should be used
6. you are returning index not position
position=index +1

//this the correct way of doing
var haystack=["hay","needle","rabbit","hat"];
for(var i=0;i<haystack.length;i++)
{
console.log(haystack[i]);
}
function findNeedle(haystack)
{
return "found needle at index"+haystack.indexOf("needle");
}
findNeedle(haystack);

Answer 2

you must return: haystack[i].indexOf("needle")
but you return only text.
so add haystack[i].indexOf("needle") in your return

Answer 3

but how do i add text which should output
fiund the needle at position x
