- * Note: In the development build, `_.template` utilizes sourceURLs for easier
- * debugging. See http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/#toc-sourceurl

- * @param {string} text The template text.
- * @param {Object} data The data object used to populate the text.
- * @param {Object} [options] The options object.
- * @param {RegExp} [options.escape] The "escape" delimiter.
- * @param {RegExp} [options.evaluate] The "evaluate" delimiter.
- * @param {Object} [options.imports] An object to import into the template as local variables.
- * @param {RegExp} [options.interpolate] The "interpolate" delimiter.
- * @param {string} [sourceURL] The sourceURL of the template's compiled source.
- * @param {string} [variable] The data object variable name.
- * @returns {Function|string} Returns a compiled function when no `data` object
- * is given, else it returns the interpolated text.
- * @example
- *
- * // using the "interpolate" delimiter to create a compiled template
- * var compiled = _.template('hello <%= name %>');
- * compiled({ 'name': 'fred' });
- * // => 'hello fred'
