Shout or Whisper? 🔊
Hi, voice wizard! 🌟 Today we make words SHOUT or whisper.
We use .toUpperCase() to shout and .toLowerCase() to whisper! 🗣️
console.log("hello".toUpperCase())Shouting with toUpperCase 📢
Add .toUpperCase() to make every letter BIG and loud!
"hi".toUpperCase() becomes "HI" 🎉
console.log("yay".toUpperCase())Whispering with toLowerCase 🤫
Add .toLowerCase() to make every letter small and quiet.
"HI".toLowerCase() becomes "hi" 🌙
console.log("QUIET".toLowerCase())Shout a Name 🧒
Let us make a name SHOUT really loud!
Change the name and turn up the volume! 🔊
console.log("milo".toUpperCase())Whisper a Word 🍃
Now let us whisper a word softly.
All small letters, very gentle. 🤫
console.log("SOFTLY".toLowerCase())Using a Box 📦
You can shout or whisper a word saved in a box!
Put a word in a box, then make it loud. 📦📢
let word = "magic"
console.log(word.toUpperCase())The Original Stays the Same 🪄
Cool trick: the box keeps its original word! Only the printed copy is loud.
The magic does not change the box itself. ✨
let word = "cat"
console.log(word.toUpperCase())

So tidy. 🧹
