Homebrew has NOT installed npm. If you later install it, you should supplement
your NODE_PATH with the npm module folder:
test do
path = testpath/"test.js"
path.write "console.log('hello');"
output = shell_output("#{bin}/node #{path}").strip
assert_equal "hello", output
output = shell_output("#{bin}/node -e 'console.log(new Intl.NumberFormat(\"en-EN\").format(1234.56))'").strip
assert_equal "1,234.56", output
if build.with? "icu4c"
output = shell_output("#{bin}/node -e 'console.log(new Intl.NumberFormat(\"de-DE\").format(1234.56))'").strip
assert_equal "1.234,56", output
