    Determine if a value is primitive.

    A value is primitive if it is of a primitive type.

    Usage

        npm install @primitive/is-primitive --save   # Install package via NPM
        yarn add @primitive/is-primitive             # Install package via Yarn
        import { expect } from "chai";
        import isPrimitive from "@primitive/is-primitive";
    
        expect(isPrimitive("Boo")).to.be.true;
        expect(isPrimitive(42)).to.be.true;
        expect(isPrimitive(new Symbol("boo"))).to.be.true;
        expect(isPrimitive(isPrimitive)).to.be.true;
        expect(isPrimitive(undefined)).to.be.true;
        expect(isPrimitive(null)).to.be.true;
        expect(isPrimitive(true)).to.be.true;
    
        expect(isPrimitive({ foo: "bar" })).to.be.false;
        expect(isPrimitive(new String("boo"))).to.be.false;

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

        if (isPrimitive(x)) {
            // IntelliSense now knows `x` is a primitive value.
            let y: Primitive = x;
        }
