JavaScript standard properties and functions in Jitterbit Design Studio
These standard JavaScript functions—part of ECMA-262 v5.1—are supported in Jitterbit JavaScripts.
Important
For enhanced performance, we recommend using JavaScript only when a Jitterbit Script equivalent is not available.
Note
- The maximum number of loop iterations allowed in Harmony is 50,000.
- The maximum number of loop iterations in Jitterbit Script Language is per each individual loop. To increase the allowed number of iterations per loop in a Jitterbit Script Language script, see Jitterbit.scripting.while.max_iterations in Scripting Jitterbit variables.
- The maximum number of loop iterations in JavaScript is per script (aggregate of all loops within one script). To increase the maximum number of loop iterations in JavaScript, see Java script loop in JavaScript.
