Given two sorted arrays, find a pair that sums up to target Javascript Solution 

// given two sorted arrays, find a pair of values, one from each array such that they add up to the target value given

const findPair = (arr1, arr2, target) => {
  if(arr1.length < 1 || arr2.length < 1){
    return null;
  }
  let i = 0;
  let j = arr2.length-1;
  let check = false;
  while (i<arr1.length && j>-1) {
    if(arr1[i] + arr2[j] < target) {
      i++;
    } else if(arr1[i] + arr2[j] > target) {
      j--;
    } else {
      check = true;
      break;
    }
  }
  if(check){
    return [arr1[i], arr2[j]];
  }
  return null;
}

console.log(findPair([0], [0], 10));
console.log(findPair([], [], 10));
console.log(findPair([0,1,2,5,8,10], [1,3,6,7,9,11], 10));

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Resolve: Uncaught TypeError: firebase.database is not a function

If you are getting the error: Uncaught TypeError: firebase.database is not a function Resolve it by including firebase-database.js in your html page as follows: <!-- The core Firebase JS SDK is always required and must be listed first --> <script defer src = "https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js" ></script> <script defer src = "https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js" ></script> That is it. Let me know if this was helpful.
