How can I add a key/value pair to a JavaScript object?
📝 Adding a Key/Value Pair to a JavaScript Object: Easy Peasy! 🚀
So, you have this awesome JavaScript object, filled with key/value pairs. 🎉 But now, you're faced with a new challenge. You want to add another key/value pair to your existing object, but you're not quite sure how to do it. No worries, my friend! I've got you covered. 💪
🧩 The Challenge: A Missing Piece 🧩
Take a look at your object literal:
var obj = {key1: value1, key2: value2};
You want to add a key3 field with a corresponding value3, but how do you achieve this? 🤔
🌟 Simple Solutions to the Rescue! ✨
📌 Option 1: Dot Notation 🌟
One way to add a new key/value pair is by using dot notation:
obj.key3 = value3;
See how beautiful and easy that was? JavaScript lets you access and add properties using the dot (.) notation. 🌈
📌 Option 2: Bracket Notation 🌟
Another option, and equally powerful, is to use bracket notation:
obj['key3'] = value3;
The bracket notation permits you to access and add new properties using strings. It's like being part of an exclusive club for creative thinkers. 🎨
That's it! You've added a new key/value pair to your JavaScript object, and the possibilities are endless. 🚀
