One of the most useful modules in Node.js is the console
module. This module provides a lot of functionality for writing debug and information statements to the console. The console
module allows you to control output to the console, implement time delta output, and write tracebacks and assertions to the console. This section covers using the console
module, which you need to know how to use in later chapters of the book.
Since the console
module is so widely used, you do not need to load it into your modules by using a require()
statement. You simply call the console function by using console.<
function>(<
parameters>)
. Table 3.3 lists the functions available in the console
module.
