Handling errors in this manner is considered bad practice [1] and an anti-pattern in computer programming. In languages with exception handling support, this practice is called exception swallowing. Errors and exceptions have several purposes:
PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language.Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core.

Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file. [9]
The only exception is that errors are reported as coming from a call to eval(), and return statements become the result of the function. Unlike some languages, the argument to eval must be a string of one or more complete statements, not just expressions; however, one can get the "expression" form of eval by putting the expression in a return ...
Review the properties, methods, and associations related to a given class. See the instances available for a given class of the examined system. Perform Queries in the WQL language. Generate an MOF file based on selected classes. Compile an MOF file to load it in the CIM repository.
WHEA "builds on the PCI Express Advanced Reporting to provide more detailed information about system errors and a common reporting structure." [4] WHEA allows third-party software to interact with the operating system and react to certain hardware events.
Vectored Exception Handling was introduced in Windows XP. [7] Vectored Exception Handling is made available to Windows programmers using languages such as C++ and Visual Basic. VEH does not replace Structured Exception Handling (SEH); rather, VEH and SEH coexist, with VEH handlers having priority over SEH handlers.
The Perl mechanism for exception handling uses die to throw an exception when wrapped inside an eval {...}; block. After the eval, the special variable $@ contains the value passed from die. Perl 5.005 added the ability to throw objects as well as strings. This allows better introspection and handling of types of exceptions.
