Though true, we do this a lot and we haven't exactly standardized on this.

I tend to use const when assigning a literal primitive to give it a better name.

    const betterNameForBool = true;
    const minimumSizeOfSomething = 15;
    const defaultDisplayString = "–";

Maybe we should start using const more for cases like this.
