Build a Username Cleaner
Use loops and string methods to clean up a messy username. You'll strip out spaces and convert everything to lowercase so it's database-ready.
YOUR TASK
Create a program that:
- Starts with a username like
"John Doe"
- Uses a loop to build a cleaned version character by character
- Skips spaces
- Converts all characters to lowercase
- Logs the cleaned result
Step-by-step:
1. const username = "John Doe";
2. let cleaned = "";
3. Loop: for (let i = 0; i < username.length; i++) {'{'}
4. const char = username[i];
5. if (char !== " ") {'{'}
6. cleaned += char.toLowerCase();
7. {'}'}
8. {'}'}
9. console.log(cleaned);
