Debugging is a process of going through the code, analyzing it, and identifying the defect in the code. Analysis can be done either with the logs or by checking the code, line by line, while it is executing the function. To check the logs, first of all, you should add the debugging statements in the code. The qooxdoo framework supports different log levels, such as,
debug, info, warn, and
error. Based on the log level set, qooxdoo generates the log messages.
