PredicType is a library of pre-built and tested predicates for TypeScript, covering various data types and operations.

/**
 * Checks if a bigint value is (or is not) a member of a set of bigints using the specified operation.
 *
 * @param source The source bigint value.
 * @param oper The membership operation to perform (e.g. 'is_one_of', 'is_not_one_of').
 * @param target The array of bigints to check membership against.
 * @returns True if the membership check is valid according to the operator, otherwise false.
 *
 * @throws {Error} If the operation is not recognized.
 *
 * @example
 * const value1 = BigInt(5);
 * const value2 = BigInt(3);
 * const arr = [BigInt(1), BigInt(2), BigInt(5)];
 *
 * bigintMembership(value1, 'is_one_of', arr); // true
 * bigintMembership(value2, 'is_not_one_of', arr); // true
 *
 * @remarks
 * Supported Operators:
 * - **IN**: value is in the target array
 * - **NOT_IN**: value is not in the target array
