Step by Step solution about How to resolve the algorithm Loops/Break step by step in the JavaScript programming language

for Loop with Break:

for (;;) {
 // Generate a random number between 0 and 19
 var a = Math.floor(Math.random() * 20);

 // Print the number
 print(a);

 // If the number is 10, break out of the loop
 if (a == 10) 
   break;

 // Generate another random number
 a = Math.floor(Math.random() * 20);

 // Print the number, even though it's not 10
 print(a);
}

Explanation: This loop will continue generating random numbers and printing them indefinitely until it generates the number 10. Once 10 is generated, the loop will break. Note that the variable a is declared inside the loop, so it's local to each iteration.

Recursive Function:

(function streamTillInitialTen() {
   // Generate a random number between 0 and 19
   var nFirst = Math.floor(Math.random() * 20);
       
   // Print the number
   console.log(nFirst);
   
   // If the number is 10, return true
   if (nFirst === 10) return true;
   
   // Print another random number
   console.log(
       Math.floor(Math.random() * 20)
   );
   
   // Recursively call the function
   return streamTillInitialTen();
})();

Explanation: This recursive function will continue generating random numbers and printing them until it generates the number 10. When 10 is generated, it will return true. If any other number is generated, it will print that number and recursively call itself.

Recursive Function with Accumulator:

console.log(
 (function streamTillInitialTen() {
   // Generate a random number between 0 and 19
   var nFirst = Math.floor(Math.random() * 20);
 
   // If the number is 10, return an array with 10
   if (nFirst === 10) return [10];
 
   // Return an array with the first number and a second random number
   return [
     nFirst,
     Math.floor(Math.random() * 20)
   ].concat(
     streamTillInitialTen()
   );
 })().join('\n')
);

Explanation: Similar to the previous recursive function, this function will continue generating random numbers and printing them, but it accumulates the numbers in an array. When 10 is generated, it returns an array with only 10. For all other numbers, it returns an array with the first number, a second random number, and the result of the recursive call. The join('\n') method is used to convert the array into a string with line breaks.

for (;;) {
  var a = Math.floor(Math.random() * 20);
  print(a);
  if (a == 10) 
    break;
  a = Math.floor(Math.random() * 20);
  print(a);
}


(function streamTillInitialTen() {
    var nFirst = Math.floor(Math.random() * 20);
        
    console.log(nFirst);
    
    if (nFirst === 10) return true;
    
    console.log(
        Math.floor(Math.random() * 20)
    );
    
    return streamTillInitialTen();
})();


console.log(
  (function streamTillInitialTen() {
    var nFirst = Math.floor(Math.random() * 20);
  
    if (nFirst === 10) return [10];
  
    return [
      nFirst,
      Math.floor(Math.random() * 20)
    ].concat(
      streamTillInitialTen()
    );
  })().join('\n')
);
