+ * Angular implements the following change detection strategies by default:

+ * - [dynamicChangeDetection]: slower, but does not require `eval()`.
+ * - [jitChangeDetection]: faster, but requires `eval()`.
+ *
+ * In JavaScript, you should always use `jitChangeDetection`, unless you are in an environment that has

+ *

+ * `jitChangeDetection` strategy at compile time.
+ *
