Intermediate Algorithm Scripting - Wherefore art thou

JavaScript

Am I right in thinking that if the boolean returns as true then it automatically puts the values into a new array? I’m not 100% sure I understand why booleans are used here.

Your code so far

function whatIsInAName(collection, source) {
  // "What's in a name? that which we call a rose
  // By any other name would smell as sweet.”
  // -- by William Shakespeare, Romeo and Juliet
  const souceKeys = Object.keys(source);

  // filter the collection
  return collection.filter(obj => {
    for (let i = 0; i < souceKeys.length; i++) {
      if (!obj.hasOwnProperty(souceKeys[i]) ||
          obj[souceKeys[i]] !== source[souceKeys[i]]) {
        return false;
      }
    }
    return true;
  });
}

// test here
whatIsInAName(
  [
    { first: "Romeo", last: "Montague" },
    { first: "Mercutio", last: null },
    { first: "Tybalt", last: "Capulet" }
  ],
  { last: "Capulet" }
);
