File Path Matcher
Build a simple file path matching utility that filters lists of file paths based on wildcard patterns.
Requirements
Create a module that exports a function matchPaths which takes an array of file path strings and a pattern string, then returns an array of paths that match the pattern.
The pattern matching should support:
- The
*wildcard which matches zero or more characters - Exact string matching for non-wildcard characters
- Patterns should match the entire path (not just substrings)
Behavior
The function should:
- Accept an array of strings as the first parameter (file paths)
- Accept a pattern string as the second parameter
- Return a new array containing only the paths that match the pattern
- Preserve the original order of matching paths
- Return an empty array if no paths match
Examples
matchPaths(['app.js', 'test.js', 'README.md'], '*.js')
// Returns: ['app.js', 'test.js']
matchPaths(['src/index.js', 'src/utils.js', 'lib/helper.js'], 'src/*.js')
// Returns: ['src/index.js', 'src/utils.js']
matchPaths(['file.txt', 'file.txt.bak', 'data.txt'], '*.txt')
// Returns: ['file.txt', 'data.txt']
matchPaths(['config.json', 'package.json'], 'test-*')
// Returns: []Implementation

API
/**
* Filters an array of file paths based on a wildcard pattern
* @param {string[]} paths - Array of file path strings to filter
* @param {string} pattern - Pattern string with * wildcard support
* @returns {string[]} Array of paths that match the pattern
*/
function matchPaths(paths, pattern) {
// Implementation here
}
module.exports = { matchPaths };Test Cases
- It matches files with a specific extension @test
const result = matchPaths(['app.js', 'test.js', 'README.md'], '*.js');
// Expected: ['app.js', 'test.js']- It matches files in a specific directory @test
const result = matchPaths(['src/index.js', 'lib/helper.js', 'src/utils.js'], 'src/*.js');
// Expected: ['src/index.js', 'src/utils.js']- It returns empty array when no matches found @test
const result = matchPaths(['config.json', 'package.json'], 'test-*');
// Expected: []- It matches with wildcard at the start @test
const result = matchPaths(['test-one.js', 'test-two.js', 'main.js'], 'test-*');
// Expected: ['test-one.js', 'test-two.js']Dependencies { .dependencies }
