if and else

Code that chooses

Every morning you make little decisions: if it's raining, take an umbrella; otherwise, wear sunglasses. Until now your code ran every line, top to bottom. Today it learns to choose.

The if statement

An if statement runs a block of code only when a condition is true.

const raining = true;

if (raining) {
  console.log("Take an umbrella ☔");
}
console.log("Have a good day!");

Change true to false and run it again. The umbrella line disappears, but "Have a good day!" stays.
