JavaScript

function createIncrement(incBy) {
  let value = 0;

  function increment() {
    value += incBy;
    console.log(value);
  }

  const message = `Current value is ${value}`;
  function log() {
    console.log(message);
  }
  
  return [increment, log];
}

const [increment, log] = createIncrement(1);
increment(); // logs 1
increment(); // logs 2
increment(); // logs 3
// Does not work!
log();       // logs "Current value is 0"
