Use node. js to check for JS syntax errors

If there are no tools and plugins to write JavaScript code to encounter syntax errors it takes time to ask a colleague how to check with node. js

Report a syntax error when testing with a browser.

1. Click the blue button in the red circle, and the next refresh will automatically debug the breakpoint when the exception is thrown.

3. After the error breakpoint, in the console with var a = code, the code is assigned to a (so printing faster), and then enter a to print out the error code

4. Copy the code inside the red quotation marks to the new JS text (such as a.js) and download the node. JS Installation
5. Open the Command window in the new JS text path and output node A.js to find the error code and the number of rows
