// Programming Question: Hash Tag Generator
//? You are required to implement a function generateHash that generates a hash tag from a given input string.
// The hash tag should be constructed as follows:

//? The input string should be converted to a hash tag format, where each word is capitalized and concatenated together without spaces.
//? If the length of the input string is greater than 280 characters or if the input string is empty or contains only whitespace, the function should return false.
//? Otherwise, the function should return the generated hash tag prefixed with #.
//* Write a function generateHash to accomplish this task.
const generateHash = (str) => {
  if (str.length > 280 || str.trim().length === 0) {
    return false;
  }
  str = str.split(" "); //[ 'my', 'name', 'is', 'Satyam', 'Singh' ]
  str = str.map((currElement) =>
    currElement.replace(currElement[0], currElement[0].toUpperCase())
  ); //currElement.charAt(0).toUpperCase() + currElement.slice(1); //currElement.slice
  str = `#${str.join("")}`;
  return str;
};

console.log(generateHash("my name is Satyam Singh"));
// 0/p = "MyNameIsSatyamSingh"
