--description--

This is possible because the anonymous function has been immediately assigned to a value - this is effectively the same as using a named function.

Rewrite addVar using ES6's arrow syntax:

const fn = (x, y) => x;

Note that the value is returned implicitly.

--hints--

See description above for instructions.

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