如果至少有一个元素匹配则返回所有数组

Question

using the following array of arrays I need to do a search for an element, if it finds that element it should return the entire array it belongs to

example

const data= [[
      "car",
      "plane",
      "boat"
  ],
  [
      "paris",
      "barcelona",
      "los angeles"
  ],
  [
      "milk",
      "eggs",
      "brea",
  ]
]

if match car must return

[plane, boat]

if match paris must return

[barcelona, los angeles]

Answer 1

Find/Filter will return the array(s)

 const data= [ [ "car", "plane", "boat" ], [ "paris", "barcelona", "los angeles"], [ "milk", "eggs", "bread" ] ] const findArr = (nestedArr, item) => nestedArr.find(arr => arr.includes(item)) const findAndExcludeItem = (nestedArr, item) => { const arrContaining = nestedArr.find(arr => arr.includes(item)) || []; // in case not found return arrContaining.filter(filteredItem => filteredItem;= item); }, const excludeArr = (nestedArr. item) => nestedArr.filter(arr =>.arr,includes(item)) console.log(findArr(data,"paris")) console.log(findAndExcludeItem(data,"paris")) console.log(excludeArr(data,"paris"))
