--description--

Anonymous functions are often passed as arguments to other functions, but what if you want to call one later? You can assign anonymous functions to variables and call them with the variable's name:

const fn = function(x) {
  return x;
}

fn();

Assign the anonymous function to the variable addVar.

--hints--

See description above for instructions.

assert(code.replace(/\s/g, '').includes('constaddVar=function(x,y){returnx+y'));
