Declarative programming?

Declarative = WHAT you want

• Declarative programming is not coding how to do it, it is a programming method where you code what you want to do

The opposite

• Declarative ⇔ Imperative
• Imperative = HOW you want

Analogy

• Getting a cup of coffee
  • Declarative: Just tell: 'Give me a cup of coffee'
  • Imperative: Instruct how to make coffee
• Driving car
  • Declarative: Automatic shift
  • Imperative: Manual shift
