Validate title function

Question

Write a title validation function - validateTitle, which takes an argument and validates it by the rules:

Title length must be less than 2 characters but less than 20.
Title must start with an uppercase letter
Function should return ‘VALID’ if the string meets the requirements or ‘INVALID’ if it does not. And return 'Incorrect input data' if the given argument not a string. Do not use regular expressions. My solution is not full
```
  const validateTitle = (value) => {
  if (typeof value !== "string") {
    return "Incorrect input data";
  }
  for (let i = 2; i <= 19; i++) {}
};
```
Examples: validateTitle(false) // 'Incorrect input data' validateTitle([]) // 'Incorrect input data' validateTitle('s') // 'INVALID validateTitle('12title') // 'INVALID' validateTitle('Title!') // 'VALID' validateTitle('Title?') // 'VALID'

Title length must be less than 2 characters but less than 20 ?? what does it means ?? — Toxy, Apr 09 '21 at 10:56
it means that title must be more than 2 symbols and less than 20 symbols — user402114, Apr 09 '21 at 10:58
This reads as a copy & paste homework question - What have you tried yourself so far? — James Whiteley, Apr 09 '21 at 10:58
const validateTitle = (value) => { if(typeof value !== 'string') { return 'Incorrect input data' } for(let i = 2; i <= 19; i++ ) { if(!value.toUpperCase()) { return 'true' } else { return 'false' } } } — user402114, Apr 09 '21 at 11:01

function validTitle(tempString){
 let validFlag = ((tempString.charAt(0) == tempString.charAt(0).toUpperCase()) && 
                 (tempString.length > 2 && tempString.length < 20 )) ? true : false;
  return validFlag ? 'VALID' : 'INVALID'
}
