Usage

    npm install @primitive/is-object --save   # Install package via NPM
    yarn add @primitive/is-object             # Install package via Yarn

    import { expect } from "chai";
    import isObject from "@primitive/is-object";

    expect(isObject(new Object())).to.be.true;
    expect(isObject({ foo: true })).to.be.true;

    expect(isObject([ 1, 2, 3 ]).to.be.false;
    expect(isObject(undefined)).to.be.false;
    expect(isObject(null)).to.be.false;

This package contains TypeScript type declarations. Furthermore, the package uses TypeScript type guards to allow type inference to influence intellisense.

    if (isObject(x)) {
        // IntelliSense now knows `x` is an object.
        let y: object = x;
    }
