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 + ' '; }```

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
)

I am stuck with this one too... what if the counting starts with 1 and not 0 (or counts down from 50 to 0) ... what value do you assign to the initial variable i?

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!
