javascript - 使用 lodash 过滤两个字符串数组

Question

我有两个字符串数组，例如:

var array = ["one", "two", "three", "six", "twelve", "thirteen", "twenty", "forty", "fifty"]

var array1 = ["on", "t"];

我想过滤数组以取出以 array1 中的任何元素开头的任何元素。因此，过滤后的数组应如下所示:

["six", "forty", "fifty"];

我还需要通过取出包含 array1 中任何元素的任何元素来过滤数组。因此，过滤后的数组应如下所示:

["six"];

现在我正在使用类似的东西:

_.filter(array, function(n){return _.map(array1, function(m){
                    return _.startsWith(n, m)})})

正在返回

[[true, false], [false, true], [false, true], [false, false], 
[false, true], [false, true], [false, true], [false, false], [false, false]];

不需要 lodash。

var array1 = ["one", "two", "three", "six", "twelve", "thirteen", "twenty", "forty", "fifty"]

var array2 = ["on", "t"];

array1=array1.filter(function(a){
  return array2.every(function(b){
    return !a.includes(b)
  })
});
