1我有以下數組：console.log(array)[ Data { sample_id: 'S001', v_id: 21, type: 'BD', sf: 'ETV5', ef: 'NTRK', breakpoint1: '8669', breakpoint2: '1728', sge: 8, ege: 19, som: 207, wgs: null, inframe: 1, platform: 'WR', rnaconf: 'High', reportable: 1, targetable: 1, path: 'C3', evidence: null, summary: 'Same as before', comments: null }, Data { sample_id: 'S001', v_id: 21, type: 'BD', sf: 'ETV5', ef: 'NTRK', breakpoint1: '8669', breakpoint2: '1728', sge: 8, ege: 19, som: 207, wgs: null, inframe: 1, platform: 'WR', rnaconf: 'High', reportable: 1, targetable: 1, path: 'C3', evidence: null, summary: 'Same as before', comments: null }, Data { sample_id: 'S001', v_id: 21, type: 'BD', sf: 'ETV5', ef: 'NTRK', breakpoint1: '8669', breakpoint2: '1728', sge: 8, ege: 19, som: 207, wgs: null, inframe: 1, platform: 'WR', rnaconf: 'High', reportable: 1, targetable: 1, path: 'C3', evidence: null, summary: 'An interesting development', comments: null } ]以及以下功能：function diffSummary(o1, o2) { res = (o1.sample_id === o2.sample_id) && (o1.v_id === o2.v_id) && (o1.type === o2.type) && (o1.sf === o2.sf) && (o1.ef === o2.ef) && (o1.breakpoint1 === o2.breakpoint1) && (o1.breakpoint2 === o2.breakpoint2); if(res && res1 && res2) { return true; } else { return false; } }上述函數檢查數組中的兩個對象是否相同，僅在它們的匯總值方面有所不同。我有以下代碼：var first = array[0];var new_array = array.filter(o => (JSON.stringify(o) !== JSON.stringify(first));var final_array = new_array.filter(o => diffSummary(o, first) === true);上面的代碼刪除了數組中與 相同的所有元素first。然后刪除所有與 first 相同但僅在匯總值方面不同的元素new_array。由于這些過濾器，我期望得到一個空數組。我已經測試過diffSummary，在比較array. 我不確定為什么array沒有過濾的最后一個元素。任何見解表示贊賞。
Javascript：過濾器函數沒有從數組中刪除預期的元素
