所以我是 javascript 和編程的新手，我在下面有一組對(duì)象。我正在嘗試生成并打印一個(gè)數(shù)組，其中包含所有獲得 80 分或更高考試成績(jī)的學(xué)生的全名（名字和姓氏用“”分隔）。有點(diǎn)像 ['James Johnson'、'Stephanie Ottesen'、'Leonard Arvan'、'Beverly Mott'、'Beatrice Jaco']。我已經(jīng)創(chuàng)建了一個(gè)單獨(dú)的數(shù)組，但是我無(wú)法弄清楚如何僅訪問(wèn)數(shù)組中的某些對(duì)象并將它們添加到我的新數(shù)組中。通過(guò)谷歌搜索，我遇到了 .map()、.reduce() 和 .filter() 方法，但我正在努力弄清楚如何采用這些方法并將它們格式化到我的程序中。任何幫助或參考將不勝感激。let students = [{fname: "Jane", lname: "Brazier", snum: "100366942", agrade: 67.59127376966494, tgrade: 64.86530868914188, egrade: 70.52944558104066}, {fname: "Ricardo", lname: "Allen", snum: "100345641", agrade: 65.80370345301014, tgrade: 75.40211705841241, egrade: 55.39348896202821}, {fname: "Mary", lname: "Hernandez", snum: "100221207", agrade: 71.20761408935981, tgrade: 71.37529197926764, egrade: 75.82038980457698}, {fname: "James", lname: "Johnson", snum: "100200842", agrade: 72.5791318299902, tgrade: 81.65883679807183, egrade: 85.19664228946989}, {fname: "Stephanie", lname: "Ottesen", snum: "100225067", agrade: 88.19738810849226, tgrade: 84.68339894849353, egrade: 82.23947265645927}, {fname: "Martin", lname: "Conway", snum: "100358379", agrade: 71.28759059295344, tgrade: 79.13194908266965, egrade: 77.61880623797336}, {fname: "Andrew", lname: "Weaver", snum: "100376243", agrade: 70.01798139244363, tgrade: 78.64811561086252, egrade: 78.68650242850617}, {fname: "Rhonda", lname: "Ford", snum: "100296902", agrade: 56.14580882764524, tgrade: 63.9209865108888, egrade: 60.186613967770334}, {fname: "Leonard", lname: "Arvan", snum: "100220616", agrade: 80.67865525396981, tgrade: 92.73557717342663, egrade: 88.32126970338336}, {fname: "William", lname: "Culler", snum: "100307637", agrade: let studentNames = [];
