strip-outer

What is strip-outer?

The strip-outer npm package is designed to remove the outermost matching substring from a given string. It is particularly useful for trimming specific characters or patterns from the start and end of strings, allowing for more precise string manipulation than traditional trim methods.

What are strip-outer's main functionalities?

Strip specific characters from the start and end of a string

This feature allows you to remove specific characters or patterns from both the start and end of a string. In the provided code sample, the 'strip-outer' package is used to remove the '---' characters from around the 'Hello World' string.

"use strict";\nconst stripOuter = require('strip-outer');\nconsole.log(stripOuter('---Hello World---', '---')); // 'Hello World'

Strip patterns using regular expressions

This feature demonstrates the ability to use regular expressions to define the pattern to be stripped from the string. In the example, all '#' characters are removed from the start and end of the 'Hello World' string.

"use strict";\nconst stripOuter = require('strip-outer');\nconsole.log(stripOuter('###Hello World###', /#+/)); // 'Hello World'

Other packages similar to strip-outer

trim

The 'trim' package offers functionality to remove whitespace from both ends of a string. While it is similar in its purpose of trimming strings, it does not offer the flexibility of removing specific characters or patterns like 'strip-outer'.

left-pad

Although 'left-pad' is more focused on adding padding to the start of a string, it is mentioned here for its relevance in string manipulation. Unlike 'strip-outer', 'left-pad' does not remove characters but adds them, serving an opposite yet related purpose.
