Compile errors

[Chuck]

I started having trouble getting 'popular.js` to compile with "Caching Repos" episode. Ther error message at the console is:

Failed to compile.

./src/components/Popular.js
  Line 63:  'error' is not defined  no-undef

Line 63 reads see here:

.catch(() => {
          console.warn('Error fetching repos: ', error)

I think the line should read the following, and it seems to work fine:

.catch(() => {
          console.warn('Error fetching repos: ', this.state.error)

Thanks for a great course and I am learning a lot.
