Unexpected 'debugger' statement.
Open

            debugger
Severity: Minor
Found in app/assets/javascripts/changePrivacy.js by eslint

disallow the use of debugger (no-debugger)

The debugger statement is used to tell the executing JavaScript environment to stop execution and start up a debugger at the current point in the code. This has fallen out of favor as a good practice with the advent of modern debugging and development tools. Production code should definitely not contain debugger, as it will cause the browser to stop executing code and open an appropriate debugger.

Rule Details

This rule disallows debugger statements.

Example of incorrect code for this rule:

/*eslint no-debugger: "error"*/

function isTruthy(x) {
    debugger;
    return Boolean(x);
}

Example of correct code for this rule:

/*eslint no-debugger: "error"*/

function isTruthy(x) {
    return Boolean(x); // set a breakpoint at this line
}

When Not To Use It

If your code is still very much in development and don't want to worry about stripping debugger statements, then turn this rule off. You'll generally want to turn it back on when testing code prior to deployment.

Duplicated Code

Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Tuning

This issue has a mass of 50.

We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.
