This app was built using Javascript, MongoDB, Express, Angular, Node, and High Charts.

Primary Features

• High Charts: High Charts is a charting library written in pure JavaScript, offering an easy way of adding interactive charts to your web site or web application.
• API calls: With a single click every job on Angel List (over 23,000) are gathered, scrubbed, and stored in a MongoDB.

• Similar Word Combinations: I built a function that adds the values and combines misspelled skills. For example, "Angular.js" is the most popular spelling so all of the "AngularJS", "Angular", and "Angular JS" properties are combined when the original object is passed through this function.

var combineSimilarWords = function (originalObject) {
  var targetObject = targetWords;
  for (var originalWord in originalObject) {
    for (var targetWord in targetObject) {
      if (targetObject[targetWord].indexOf(originalWord) > -1) {
        originalObject[targetWord] = originalObject[targetWord] + originalObject[originalWord];
        delete originalObject[originalWord];
      }
    }
  }
  return originalObject;
};
