/**
 * @param source The input JavaScript source code.
 * Type: string or an array of strings (each element is interpreted as a newline)
 * @example `JSHINT(["'use strict';", "console.log('hello, world!');"]);`
 *
 * @param options The linting options to use when analyzing the source code.
 * Type: an object whose property names are the desired options to use and whose property values are the configuration values for those properties.
 * @example `JSHINT(mySource, { undef: true });`
 *
 * @param predef variables defined outside of the current file; the behavior of this argument is identical to the globals linting option.
 * Type: an object whose property names are the global variable identifiers and whose property values control whether each variable should be considered read-only
 * @example `JSHINT(mySource, myOptions, { jQuery: false });`
