/*
    Now loop that array we created
    there are three parts in this for loop construct
    var index = 0; // this is our counter 
    than follows a condition
    index < source_array.length
    as long as this is true we do the third part
    index = index + 1; // we increment the index by one
    
    Than the condition loop block { } is executed
    when the block is done he will again check if the condition
    index < source_array.length
    is still true. If so increment by one and execute the block { }
    
    you can stop a loop by using break;
    
    like:
    
    if(index == 5){
    break;
    }
    
    or step over one index by using
    
    if(index == 5){
    continue
    }
    
    Play with it a lot. Don't worry you wont go blind
