JavaScript is an object-oriented scripting language designed for embedding into other products and applications. The language is divided into the core JavaScript and client-side JavaScript. The client-side JavaScript is designed to manipulate objects in Web browser, and the core language can be used in multi-purpose environments.
Inside the Sybase IQ ETL environment, core JavaScript is embedded to allow manipulation of objects to provide programmatic control over them.
The core JavaScript functionality is enriched by grid functions, which enhance the flexibility of the language. The JavaScript Editor and Debugger let you interactively edit, debug, and execute JavaScript code.
The JavaScript Editor and Debugger is mainly used (but not restricted) to set up transformation rules on incoming data. Inside the JavaScript Editor and Debugger, the scripts entered can be executed and tested using a single input record.
The JavaScript Editor and Debugger offers the following features:
Color-coded syntax for better readability
Watchlist to control the assigned values of variables and attributes when running or stepping through the code
Multiple user-definable Breakpoints to stop code execution at any line positions
User-definable Go points to arbitrarily choose the position from which a code shall be executed
Step mode to execute the code line by line
Step-over during debugging
Evaluation of JavaScript expressions
Verify the result of code execution
