{"library":"lodash.isnull","title":"lodash.isnull","description":"lodash.isnull is a standalone npm package providing the `_.isNull` utility function from the Lodash library. This specific package, currently at version 3.0.0, offers the implementation of `_.isNull` as it existed in Lodash v3. While the main Lodash library has advanced to v4.x, this modular package has not seen a corresponding major update, meaning it does not incorporate newer features, bug fixes, or security patches introduced in Lodash v4. It was designed for environments where importing only specific Lodash functions was desirable to reduce bundle size, prior to widespread adoption of `lodash-es` and modern tree-shaking tools. Release cadence for `lodash.isnull` is effectively halted, as its last update was 11 years ago, aligning with the Lodash v3 era. Its primary differentiator is its singular focus on the `isNull` check, offering a minimal footprint if that's the *only* Lodash utility required and you are explicitly targeting Lodash v3 compatibility.","language":"javascript","status":"abandoned","last_verified":"Sun Apr 19","install":{"commands":["npm install lodash.isnull"],"cli":null},"imports":["import isNull from 'lodash.isnull'","const isNull = require('lodash.isnull');","const _ = require('lodash'); // Then use _.isNull"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"import isNull from 'lodash.isnull';\n\nconsole.log('Checking for null values:');\n\nlet value1 = null;\nlet value2 = undefined;\nlet value3 = 0;\nlet value4 = '';\nlet value5 = false;\nlet value6 = {};\n\nconsole.log(`Is value1 (null) null? ${isNull(value1)}`);\nconsole.log(`Is value2 (undefined) null? ${isNull(value2)}`);\nconsole.log(`Is value3 (0) null? ${isNull(value3)}`);\nconsole.log(`Is value4 ('') null? ${isNull(value4)}`);\nconsole.log(`Is value5 (false) null? ${isNull(value5)}`);\nconsole.log(`Is value6 ({}) null? ${isNull(value6)}`);\n\n// Demonstrating CommonJS usage for older environments\nconst isNullCJS = require('lodash.isnull');\nconsole.log(`\\nCJS check: Is null null? ${isNullCJS(null)}`);","lang":"javascript","description":"This quickstart demonstrates how to import and use the `isNull` function from `lodash.isnull` to check if various values are strictly `null` in both ES Module and CommonJS contexts.","tag":null,"tag_description":null,"last_tested":null,"results":[]},"compatibility":null}
