Bug Report

Describe the current, buggy behavior

The wp i18n make-pot fails to parse a JS file with the following content (simplified):

8e-5.toFixed(3)

The result is:

Debug (make-pot): Could not parse file test.js: Invalid exponential notation (line 1, column 5) (0.097s)

Describe how other contributors can replicate this bug

Create a test.js file with the mentioned content inside a WordPress plugin and run wp i18n make-pot.

Describe what you would expect as the correct outcome

The file is parsed and processed by the wp i18n command.
