TypeError: Path must be a string. Received undefined

when saving 06-concat.js (at the first task) the following error pops up:

/home/functionalJS/node_modules/mocha-coderoad/lib/runner.js:36 test error path.js:8
    throw new TypeError('Path must be a string. Received ' +
    ^

Thanks for pointing out that issue!

I'll release a new version of the tutorial with a fix, but if you don't want to lose your current progress for now, try this:

go into node_modules/coderoad-functional-school/tutorial/1/06/01-concat.spec.js and make the following change:

// loadGlobal('data/courses2.json'); 
loadGlobal('courses', 'data/courses2.json');
