Need support for the 3 dots operator to install tensorflow/tfjs-node #620

• Version: v10.13.0
• Platform:Windows 10.0.17763.316
• Subsystem:

Looks like ChakraCore might need to add support for the 3 dots operator (spread operator)?
Get the below error for both 10.13.0 & latest nightly.
Here's the file
