Renaming Properties

js-rename-props.js

// By combining the techniques above, a function can be created to rename properties.
// Imagine there are some objects with an uppercase ID that should be lowercase. 
// Start by destructuring ID out of the object. Then add it back as id while object is being spread.

const renamed = ({ ID, ...object }) => ({ id: ID, ...object });

const user = {
  ID: 500,
  name: "Bob Fossil"
};

renamed(user); // { id: 500, name: 'Bob Fossil' }
