This commit contains two types of fixes.
1) Sentences with two spaces after the period, which is disallowed
in GitLab's style guide

2) Usage of 'Node.JS' - not only does this usage trigger the
sentence spacing rule, it's actually incorrect according to the
trademark. It should be 'Node.js' in sentence case - this usage
also passes the sentence spacing test, since it only looks for
capital letters immediately following a period.
