How to display js constant in pug?

Question

JavaScript

Good day.
Sorry for this question, but how to display a constant in index.pug
Let's say I store some settings in a separate JS file - I define a constant there. The question is how to get it out.

Answer 1

Do you need to output the constant as a constant/variable, or substitute its value in the JS code? To make it so If as a variable, then, as in normal HTML + JS, you define a variable in the file, include the file in the head tag and use it further. If as a string, then nothing from the JS file. You can store _config.pug in a separate pug file and then connect and use it as a regular variable.
