Test-Driven React: JSX test without semicolon FAILS (55)

@TrevorBurnham

For us who don’t like to use semicolons with JavaScript, the hello.test.js example on page 55 will FAIL when no semicolons are used!

For this test to PASS there must be a semicolon at line 5, like this jest.spyOn(React, 'createElement');.

This could have been pointed out in the book.
