// 2: Use any loop. Given the iterable let str='hello,dear.friend! nice,to.see you!', 
// replace each dot and comma with space. The final output should be: hello dear friend! nice to see you!.

let str = 'hello,dear.friend! nice,to.see you!'

// version 1:

  }
  newStr += char
}
console.log(newStr); // hello dear friend! nice to see you!

  if(str[i] === '.' || str[i] === ','){
    stringy += ' ';
  } else {
    stringy += str[i];

}
console.log(stringy); // hello dear friend! nice to see you!

console.log('----------------------------------------------------');

// version 3:

  if(str[i] === ',' || str[i] === '.'){
    str = str.substr(0,i) + ' ' + str.substr(i+1);
