Easiest Approach for Hash/Equal Implementation for Struct with Date Objects

export class EodRequest extends Data.Class<{ dateFrom: Date; dateTo: Date; symbol: NonEmptyString255 }> {
  // TODO: This is rediculous, it's required because Dates are compared by instance
  [hashSymbol] = () =>
    Hash
      .structure({
        dateFrom: this.dateFrom.getTime(),
        dateTo: this.dateTo.getTime(),
        symbol: this.symbol
      });

  [equalSymbol](this: EodRequest, that: Equal): boolean {
    // yuk
    if (!(that instanceof EodRequest)) return false
    const self = { dateFrom: this.dateFrom.getTime(), dateTo: this.dateTo.getTime(), symbol: this.symbol }
    const thatt = { dateFrom: that.dateFrom.getTime(), dateTo: that.dateTo.getTime(), symbol: that.symbol }

    const selfKeys = Object.keys(self)
    const thatKeys = Object.keys(thatt as object)
    if (selfKeys.length !== thatKeys.length) {
      return false
    }
    for (const key of selfKeys) {
      if (!(key in (thatt as object) && Equal.equals((self as any)[key], (thatt as any)[key]))) {
        return false
      }
    }
    return true
  }
}
