Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during compilation.

• Variable declarations are hoisted to the top of their scope but not their initializations.

• Function declarations are fully hoisted, including their definitions.

• Hoisting can lead to unexpected behavior if not understood properly.

Different datatypes in JavaScript include string, number, boolean, object, array, null, and undefined.

• String: 'hello'

• Number: 42

• Boolean: true or false

• Object: { key: value }

• Array: [1, 2, 3]

• Null: null

• Undefined: undefined
