title: What does for i = 1 ; i <= power ; 1 += 1) { mean?
body: <p>Sorry for pretty basic question.</p>
  
  <p>Just starting out. Using flowgorithm to write code that gives out a calculation of exponential numbers.</p>
  
  <p>The code to do it is:</p>
  
  <pre><code>function exponential(base, power) {
      var answer;
      answer = 1;
      var i;
      for (i = 1 ; i &lt;= power ; i+= 1) {
          answer = answer * base;
          }
      return answer;
      f
  </code></pre>
  
  <p>then it loops up to the number of power. And i just understand that in the flowgorithm chart but i dont understand the code for it.
  what does each section of the for statement mean? 
  i = 1 to power, i just need help understanding how it is written? What is the 1+= 1 bit?</p>
  
  <p>Thanks.</p>
