Look at the function in the editor: it takes an array of keys and an object, and uses reduce to copy only the object with the specified keys. What would you name this function?

A function that takes an array of keys and an object, then uses reduce to create a new object containing only the specified keys is commonly called pick.

This name is widely used in various libraries (for example, Lodash) and accurately reflects the essence — "picking" only the necessary fields from an object.

Example in JavaScript:

function pick(keys, obj) {
  return keys.reduce((acc, key) => {
    if (key in obj) {
      acc[key] = obj[key];
    }
    return acc;
  }, {});
}

This name is intuitively understandable and aligns with common terminology.
