title: Count the prime numbers from 2 to 100 with simpler code than this
body: <p>It has to be with just functions, variables, loops, etc (Basic stuff). I'm having trouble coming up with the code from scratch from what I've I learned so far(Should be able to do it).  Makes me really mad :/. <strong>If you could give me step by step to make sure I understand I'd really really appreciated.</strong> Thanks a bunch in advanced.</p>
  
  <p>How could I get the same result with a simpler code than this one:</p>
  
  <pre><code>var primes=4; 
  for (var counter = 2; counter &lt;= 100; counter = counter + 1)
  {
      var isPrime = 0;
      if(isPrime === 0){ 
          if(counter === 2){console.log(counter);} 
          else if(counter === 3){console.log(counter);} 
          else if(counter === 5){console.log(counter);} 
          else if(counter === 7){console.log(counter);} 
          else if(counter % 2 === 0){isPrime=0;} 
          else if(counter % 3 === 0){isPrime=0;} 
          else if(counter % 5 === 0){isPrime=0;} 
          else if(counter % 7 === 0){isPrime=0;}
          else {
              console.log(counter);
              primes = primes + 1;
          }
      }
  }
  console.log("Counted: "+primes+" primes");
  </code></pre>
