+/**
+ * Creates a compiled template function that can interpolate data properties
+ * in "interpolate" delimiters, HTML-escape interpolated data properties in
+ * "escape" delimiters, and execute JavaScript in "evaluate" delimiters. Data
+ * properties may be accessed as free variables in the template. If a setting
+ * object is provided it takes precedence over `_.templateSettings` values.
+ *
+ * **Note:** In the development build `_.template` utilizes
+ * [sourceURLs](http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/#toc-sourceurl)
+ * for easier debugging.
+ *
+ * For more information on precompiling templates see
+ * [lodash's custom builds documentation](https://lodash.com/custom-builds).

+ * [Chrome's extensions documentation](https://developer.chrome.com/extensions/sandboxingEval).

+ * @category String
+ * @param {string} [string=''] The template string.
+ * @param {Object} [options] The options object.
+ * @param {RegExp} [options.escape] The HTML "escape" delimiter.
+ * @param {RegExp} [options.evaluate] The "evaluate" delimiter.
+ * @param {Object} [options.imports] An object to import into the template as free variables.
+ * @param {RegExp} [options.interpolate] The "interpolate" delimiter.
+ * @param {string} [options.sourceURL] The sourceURL of the template's compiled source.
+ * @param {string} [options.variable] The data object variable name.
+ * @param- {Object} [guard] Enables use as an iteratee for functions like `_.map`.
+ * @returns {Function} Returns the compiled template function.
