What to do with errors found through Gulp?

Question

JavaScript

I'm learning Gulp.
I want to bind the timeline plugin to the project .
After adding any js files and running gulp I get a bunch of errors. When I connected all the files, I got more than 100,000 detected errors. To determine the cause, I disabled all scripts and left only main.js as a result of 15 errors. It contains a small script.

$(document).ready(function () { 
      var tg1 = $("#placement").timeline({
         "data_source":"json_tests/js_history.json",
         "min_zoom":15,
         "max_zoom":60, 
     });
   });

Here is the message from the terminal:

[17:10:33] ESLintError in plugin 'gulp-eslint'

Perhaps ESLintError is too picky or I'm somehow not connecting the scripts in the right way.

Answer 1

correct the mistakes. Write in the eslint settings the global variables that you use ($). Replace the quotes as specified in the eslint settings, etc.
If you don't care about coding style, just disable eslint. In general, most of these problems can be fixed automatically (from version 2.0.0 of eslint or by means of the IDE + editorconfig).
