Exclude function (not an entire file) from JavaScript code coverage

Use below lines of code to ignore code for coverage.

/* istanbul ignore if */      ---skips the "if thing" in the source code
/* istanbul ignore else */    ---skips the "else thing" in the source code
/* istanbul ignore next */    ---skips the "next thing" in the source code

It appears that the guy behind Istanbul has added support for ignoring specific sections of code from coverage analysis. Really useful!
