Question 1

How to filter an array of strings to exclude certain patterns using matcher?

Accepted Answer

Use the `matcher` function with negated patterns starting with `!`. For example, `matcher(['foo', 'bar', 'moo'], ['!*oo'])` returns `['bar']`, as shown in the README, allowing easy exclusion without regex.

Question 2

Should I use matcher or regex for simple string matching in JavaScript?

Accepted Answer

Matcher is better for basic wildcard patterns where regex is overkill, offering a simpler syntax and likely better performance. However, regex is necessary for advanced features like groups or lookaheads.

Question 3

Can matcher handle case-insensitive matching by default?

Accepted Answer

Yes, matcher defaults to case-insensitive matching, but you can enable case-sensitive matching with the `caseSensitive: true` option, as demonstrated in the API examples for precise control.

Question 4

Is matcher suitable for matching file paths in a Node.js app?

Accepted Answer

Matcher can handle simple file name matching, but it lacks path-specific features like recursive wildcards. For full path matching, consider dedicated glob libraries like `minimatch`.

Question 5

How does matcher compare to minimatch for wildcard matching?

Accepted Answer

Matcher is more minimal and focused on basic wildcard and negation patterns with better performance for simple cases. Minimatch offers broader glob-like features, so choose based on your need for simplicity versus advanced patterns.

Question 6

What happens if I pass an empty array or string to matcher?

Accepted Answer

The README shows that `matcher([], [])` returns `[]` and `isMatch([], [])` returns `false`, handling edge cases gracefully without errors, but it's important to validate inputs for expected behavior.
