{"library":"should-util","title":"should.js Utility Functions","description":"should-util is a foundational utility library within the should.js assertion ecosystem. It provides a collection of core helper functions, primarily type-checking utilities (e.g., `isString`, `isArray`, `isFunction`) and a `deepEqual` comparison function. The package itself is highly stable, having been at version 1.0.1 since its initial releases over a decade ago, with the last code commit occurring 7 years prior. As such, it follows a 'maintenance' release cadence, receiving no active development or new features. Its primary differentiator is its integral role in the should.js assertion library, offering common, reusable functionalities that are robust and well-tested, though not independently maintained for general-purpose use. It is predominantly a CommonJS module, reflecting its age.","language":"javascript","status":"maintenance","last_verified":"Sun Apr 19","install":{"commands":["npm install should-util"],"cli":null},"imports":["import { isString } from 'should-util'","import { deepEqual } from 'should-util'","import { isArray } from 'should-util'"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"import { isString, isArray, deepEqual } from 'should-util';\n\n// Example 1: Type checking a string\nconst myString = 'Hello, world!';\nconsole.log(`'${myString}' is a string: ${isString(myString)}`);\n// Expected: 'Hello, world!' is a string: true\n\n// Example 2: Type checking an array\nconst myArray = [1, 2, 3];\nconsole.log(`${JSON.stringify(myArray)} is an array: ${isArray(myArray)}`);\n// Expected: [1,2,3] is an array: true\n\n// Example 3: Deep equality comparison\nconst objA = { a: 1, b: { c: 2 } };\nconst objB = { a: 1, b: { c: 2 } };\nconst objC = { a: 1, b: { c: 3 } };\n\nconsole.log(`objA deepEqual objB: ${deepEqual(objA, objB)}`);\n// Expected: objA deepEqual objB: true\nconsole.log(`objA deepEqual objC: ${deepEqual(objA, objC)}`);\n// Expected: objA deepEqual objC: false\n\n// Example 4: Demonstrating other exports\nimport util from 'should-util'; // For older bundlers or direct CommonJS require\nconsole.log(`Is null undefined? ${util.isUndefined(null)}`);\nconsole.log(`Is undefined undefined? ${util.isUndefined(undefined)}`);","lang":"typescript","description":"Demonstrates importing and using `isString`, `isArray`, and `deepEqual` for type checking and object comparison, key utilities from the package.","tag":null,"tag_description":null,"last_tested":null,"results":[]},"compatibility":null}
