🚀 New JavaScript ES2024 Features You Should Know

I've just finished putting together a comprehensive guide on the latest JavaScript features that landed in ES2024. Some really exciting additions that will change how we write modern JavaScript!

Array.prototype.with() method
Temporal API improvements
RegExp v flag 
// New Array.with() method
const arr = [1, 2, 3, 4, 5];
const newArr = arr.with(2, 'updated');
console.log(newArr); // [1, 2, 'updated', 4, 5]

Just finished my first React project! 🎉 Built a task management app with drag & drop functionality using React DnD. The learning curve was steep but so worth it!

This looks amazing! I'm working on a similar project. How did you handle the state management for the drag and drop?

@Mike Johnson I used React Context for global state and local state for drag operations. Happy to share the code structure if you're interested!

🐍 Python tip: List comprehensions vs Generator expressions

Quick comparison for beginners wondering about the difference:

List Comprehension
# Creates a list in memory
squares = [x**2 for x in range(1000)]
print(type(squares))  #
Generator Expression
# Creates a generator object
squares = (x**2 for x in range(1000))
print(type(squares))  #

Use generators for large datasets to save memory! 🧠
