Use fewer type assertions

[danielnixon]

For example,

  // eslint-disable-next-line @typescript-eslint/consistent-type-assertions
  const d = new Date(value as number | string | Date);

can probably become:

const d = new Date(typeof value === "string" ? value : +value);

(courtesy of:)

    /**
     * Converts a Date object to a number.
     */
    [Symbol.toPrimitive](hint: "number"): number;
