打字稿中嵌套 switch 语句的替代方案

问题描述

我正在尝试为我的 switch-case 考虑任何替代方案，因为它很长我有一个嵌套的 switch case，看起来像这样 我正在尝试为我的开关盒考虑任何替代方案，因为它很长我有一个嵌套的开关盒，看起来像这样

switch (currentTab) {
            case pending:
                switch (status) {
                    case approved:
                    case denied:
                        break;

                    case partialApproved:
                        finalUpdatedInvoiceAmount = updatedInvoiceAmount - (feeAmount - (approvedFeeAmount || 0));
                        break;
                }
                break;

            case approved:
                switch (status) {
                    case denied:
                    case partialApproved:
                        finalUpdatedInvoiceAmount = updatedInvoiceAmount - (feeAmount - (approvedFeeAmount || 0));
                        break;
                }
                break;

            case denied:
                switch (status) {
                    case approved:
                    case partialApproved:
                        finalUpdatedInvoiceAmount = oldApprovedFeeAmount ? updatedInvoiceAmount + (feeAmount - oldApprovedFeeAmount) : updatedInvoiceAmount - (feeAmount - (approvedFeeAmount || 0));
                        break;
                }
                break;

            case partiallyApprovedTab:
                switch (status) {
                    case approved:
                    case denied:
                    case partialApproved:
                        finalUpdatedInvoiceAmount = oldApprovedFeeAmount ? updatedInvoiceAmount + (feeAmount - oldApprovedFeeAmount) : updatedInvoiceAmount - (feeAmount - (approvedFeeAmount || 0));
                        break;
                }
                break;
        }

这是另一种可能性吗？由于代码非常庞大，以后可能会出现其他情况。
