Get item from list based on any String

pickEntryByString.js

// Get item from list based on any String
// Example:
// var arr = [0, 1, 2, 3, 4, 5, 6];
// pickValueByString(arr, "Text");       // >> 1
// pickValueByString(arr, "text");       // >> 5 
// pickValueByString(arr, "other text"); // >> 2
// pickValueByString(arr, "Text");       // >> 1

function byteValue(str) {
  var totalBytes = 0;
  var character;
  var stack;
  var i;
  var stringLenght = str.length;

  // From: https://stackoverflow.com/questions/1240408/reading-bytes-from-a-javascript-string
  for (i = 0; i < stringLenght; i++ ) {
    character = str.charCodeAt(i);
    stack = [];
    do {
      stack.push( character & 0xFF );  // push byte to stack
      character = character >> 8;      // shift value down by 1 byte
    }
    while ( character );
    totalBytes += +stack;
  }

  return totalBytes;

  var arrayLength = array.length;
