Constant Naming Convention
Constant naming convention
Constants are planned to be non-changing variables. It is best to practice to distinguish constants from other variables and the best way to write them is in UPPERCASE (capital letters).
// UPPERCASE const SECONDS = 60; const MINUTES = 60; const HOURS = 24; const DAY = SECONDS * MINUTES * HOURS; console.log(DAY);
Oppgave
Swipe to start coding
Store the value of pi in the constant and name it with an uppercase and show it on the console.
