+## jerry_run_all_enqueued_jobs
+
+**Summary**
+
+Run enqueued Promise jobs until the first thrown error or until all get executed.
+
+**Prototype**
+
+```c
+jerry_value_t
+jerry_run_all_enqueued_jobs (void)
+```
+
+- return value - result of last executed job, may be error value.
+
+**Example**
+
+```c
+{
+  jerry_init (JERRY_INIT_EMPTY);
+
+  const jerry_char_t script[] = "new Promise(function(f,r) { f('Hello, World!'); }).then(function(x) { print(x); });";
+  size_t script_size = strlen ((const char *) script);
+
+  jerry_value_t parsed_code = jerry_parse (script, script_size, false);
+  jerry_value_t script_value = jerry_run (parsed_code);
+  jerry_value_t job_value = jerry_run_all_enqueued_jobs ();
+
+  jerry_release_value (job_value);
+  jerry_release_value (script_value);
+  jerry_release_value (parsed_code);
