Create a script that logs the typeof result for different values:
console.log(typeof 42)
console.log(typeof "hello")
console.log(typeof true)
console.log(typeof undefined)
console.log(typeof null)
console.log(typeof [])
console.log(typeof {})
console.log(typeof function() {})
Notice how null and arrays report as "object". Understanding typeof behavior helps you debug type-related issues.
