Tell us what’s happening:
I’m just starting and I’m at a stand still. it asked me to change the Var of a & b to 6 & 15 and to change c to I am a String so I did what I thought was right and when I went to click run test it will not update. what should I do?

Your code so far


// Only change code below this line
var 6;
var 15;
var I am a String;
// Only change code above this line

a = a + 1;
b = b + 5;
c = c + " String!";

Challenge: Understanding Uninitialized Variables

Link to the challenge:

2

You need to Initialize a, b, and c to the correct values so that they have the desired end values after the three additions given at the bottom.

3

So like this?

var a = 6;
var b = 15;
var c = I am a String

4

You deleted the variable names.

5

Not quite, you need to pick the right start value to get the desired end value.

// Only change code below this line
var a = A_NUMBER_THAT_WILL_MAKE_6_WHEN_YOU_ADD_1;
var b = A_NUMBER_THAT_WILL_MAKE_15_WHEN_YOU_ADD_5;
var c = A_STRING_THAT_WILL_MAKE_I_AM_A_STRING_WHEN_YOU_ADD_STRING;
// Only change code above this line

a = a + 1;
b = b + 5;
c = c + " String!";
6

like this?

// Only change code below this line
var a = 3
var b = 5
var c = “I am a string”

7

Well,

3 + 1 === 4 !== 6, so your value for a won’t work

5 + 5 === 10 !== 15, so your value for b won’t work

"I am a string" + " String!" === "I am a string String!" !== "I am a string!", so your value fol c won’t work

8

oh I see like this then?

// Only change code below this line
var a = 5
var b = 10
var c = “I am a”

9

There you go! I think that should do it.

10

for some reason is that the var would be added twice

11

Just be careful, you have ‘smart quotes’ there when you really need regular quotes: "

For QWERTY keyboards, yeah. Sometimes phones or other devices auto correct to the smart quotes “” instead of regular, normal quotes "".
