While implementing a feature to display text based on post creation time (or more precisely, trigger text next to creation time for modified posts), I came across a function called Parser. I came across a function called Parser and wanted to share what I learned.

Concept

A Parser is a software tool or module that analyzes a given input data and separates it into meaningful components. A parser takes a series of strings or tokens as input, analyzes them according to grammar rules, and converts the results into a tree or abstract syntactic representation.

Main uses

Used in programs such as compilers, interpreters, database query processors, markup language processors, etc. These programs analyze input according to specific grammar rules, tokenize it accordingly, or generate a syntax tree to interpret or execute its meaning.

Conclusion

Programs can effectively process input data and understand or execute the meaning of the data.
