🔧 Technical Implementation

Core Functions

Data Processing

// Database iteration with for...in
for (const key in notesDatabase) {
    // Process each note
}

// Category processing with for...of
for (const category of uniqueCategories) {
    // Handle unique categories
}

// Metadata processing with forEach
notesMetadata.forEach((value, key) => {
    // Process note metadata
});

CRUD Operations

createNote(title, content, categories, showMessage)
updateNote(id, title, content, categories)
archiveNote(id)
deleteNotePermanently(noteId)
searchNotes(searchTerm)
filterByCategory(category)

UI Management

showNoteModal(note)
toggleNoteExpansion(noteId)
updateSelectedCategories()
updateAvailableCategories()

Object Methods Usage

// Get all database keys
const keys = Object.keys(notesDatabase);

// Get all note objects
const values = Object.values(notesDatabase);

// Process key-value pairs
Object.entries(notesDatabase).forEach(([key, value]) => {
    // Handle each entry
});
