  • Instance constructor for use where async instantiation is not possible. Where possible, prefer the static create method over use of this constructor directly as no initialization (feature detection) is able to be done here

    Parameters

    • desiredFeatures: (
          | "bigInt"
          | "bulkMemory"
          | "exceptions"
          | "extendedConst"
