var input=  [1,0,1,1,1,0];
var counter= 0; // Ones counter
var lastValue= null;  // Start lastValue as null

for(var i=0; i< input.length; i++){

     && lastValue === input[i] // AND is consecutive with previous element? 
     || (lastValue === null && input[i] === 1) // OR the first element is null? lastValue= null means i'm at first element  
  ){
    // Raise counter by 1
    counter++;

  // Now point last value as current element
  lastValue= input[i];
