Uncomment

Uncomment is a term used in computer programming to describe the action of removing comment markers from a line or block of code. Comments are sections of text within a program that are ignored by the compiler or interpreter. They are typically used to explain the code, add notes, or temporarily disable code for testing purposes.

When code is commented out, it is effectively deactivated. Uncommenting this code re-enables it, causing it to be processed by the programming language's tools. The specific syntax for comments varies between programming languages. For example, in Python, a '#' symbol indicates a single-line comment, while in C++, Java, and JavaScript, '//' denotes a single-line comment and '/* ... */' denotes a multi-line comment.

To uncomment code, a programmer would locate the comment markers and delete them, or in some development environments, use a specific function or keyboard shortcut to perform the action. This is a common task when debugging, refining code, or restoring previously disabled functionality. It allows developers to easily switch between active and inactive code segments without having to retype the entire section.
