Organizing Parsed JSON Data with JavaScript: Using the _.each function for Sorting

Question

Organizing Parsed JSON Data with JavaScript: Using the _.each function for Sorting

var Scriptures = JSON.parse( fs.readFileSync(scriptures.json, 'utf8') );
_.each(Scriptures, function (s, Scripture) {
  return Scripture;
});

This code extracts and displays the names of each book from a collection of scriptures (e.g., Genesis, Exodus, Leviticus). The issue at hand is that the books in the JSON file are not arranged properly. Numerous attempts have been made to sort them within the _.each loop without success. An approach like this:

correctlyOrderedIndex.indexOf(Scripture) - correctlyOrderedIndex.indexOf(s);

accurately retrieved the index of each item, yet sorting them inside the _.each loop appears to be impossible. Is there a way to pre-arrange the order before entering the _.each loop or perhaps an alternative method to sort them while looping through?

Answer №1

Sorting inside the each function is not recommended as it may be too late in the process. However, you can sort before using _.each:

var Library = JSON.parse( fs.readFileSync(library.json, 'utf8') );
Library.sort(); // sorts the array in place
_.each(Library, function (item, index) { 
  return index; 
});

Alternatively, you can pass the sorted values as a parameter to each:

var Library = JSON.parse( fs.readFileSync(library.json, 'utf8') );
_.each(Library.sort(), function (item, index) { 
  return index; 
});
