closure_reads.js

function addBase(value) {
  return value + base;
}

const total = addBase(5);

console.log("base=" + base);
console.log("total=" + total);

closure-reads A closure lets a function remember variables from the scope where it was created. Here the function reads `base` from the outer scope.
