Package description
The `isobject` npm package is a simple utility for checking if a value is an object. This can be particularly useful when you need to differentiate between objects and other types of values in JavaScript, such as arrays, null, or primitives (e.g., numbers, strings, booleans).
Object Type Checking
This feature allows you to check if a given value is an object. It returns `true` for objects and `false` for arrays, null, or any other type. This is particularly useful for type checking in applications where distinguishing between objects and other types is necessary.
const isObject = require('isobject');
console.log(isObject({})); // true
console.log(isObject([1, 2, 3])); // false
console.log(isObject(null)); // false
console.log(isObject('hello')); // falseSimilar to `isobject`, `lodash.isplainobject` checks if a value is a plain object, that is, an object created by the Object constructor or one with a [[Prototype]] of `null`. It differs from `isobject` by specifically checking for plain objects, whereas `isobject` is more general in its check for any object type.
This package offers functionality similar to `lodash.isplainobject` and is focused on identifying plain objects. It's a more specialized check compared to `isobject`, which does not differentiate between plain objects and other object types like `Date` or `RegExp` instances.
