What am I doing wrong here?

```let i; let text;

// 1. Write a while loop to build a string of numbers from 0 to 4, // separated by spaces, and store the string in the variable `text`. print('1st Loop:'); text = '';

// Write 1st loop here:

while (i <= 4) { i++; text += i + ' '; }```

You need to assign a value to your initial `i` variable

```let i = 0 // Sets the variable to equal 0 as a number so that it may be incremented
let text = '' // Sets the variable as a string

while (i <= 4) {
i += 1 // Increments the variable
text += i // adds the number to a string (which results in a string)
}
```

(You really are only missing the initial assignment for the variable `i`)

thank you, I thought I tried this but I suppose not I know this is way old, but hopefully it may help anyone else struggling with this. There are two ways I know of to do this:

1 - initialize the variable at which number you want the count to start. So if you want your count to start at 1, it would be:

let i = 1 or var i = 1

The output in that case for this program would be: 1 2 3 4

2 - increment the count before adding it to the counter. That would look like this:

var i = 0;

while ( i <= 4 ) { i += 1 ; text += (i + " "); }

Following the code shows that as long as the variable i is less than or equal to 4, the program will increase the variable by 1 and then add it to the text string. This will also result in the output of 1 2 3 4.

Hope that helps!
