"boat"
],
[

"barcelona",
"los angeles"

"headphone",
"phone",
"camera",
]
]

if match "ca"必须返回

[car, cartago, camera]

if match "ne"必须返回

[plane, headphone, phone]

Answer 1

平放数组并检查子字符串是否包含在每个元素

const data= [[      "car",      "plane",      "boat"  ],  [      "cartago",      "barcelona",      "los angeles"  ],  [      "headphone",      "phone",      "camera",  ]]
let a = data.flat().filter(v => v.includes('ca'))
console.log(a)
let b = data.flat().filter(v => v.includes('ne'))
console.log(b)
