最好的答案是: 这也是不区分大小写的

    var specsFilter = [.....];
    var yourString = "......";

    //if found a match
    if (specsFilter.some((element) => { return new RegExp(element, "ig").test(yourString) })) {
        // do something
    }

let obj = [{name : 'amit'},{name : 'arti'},{name : 'sumit'}];
let input = 'it';

使用滤镜:

obj.filter((n)=> n.name.trim().toLowerCase().includes(input.trim().toLowerCase()))

借鉴T.J. Crowder的解决方案，我创建了一个原型来处理这个问题:

Array.prototype.check = function (s) {
  return this.some((v) => {
    return s.indexOf(v) >= 0;
  });
};

const str = '此字符串是否包含下面数组中的一个或多个字符串?'; Const arr = ['one'， 'two'， 'three']; Const包含= arr。Some (element => { If (str.includes(element)) { 返回true; ｝ 返回错误; })； console.log(包含);/ /正确的

var str = "A for apple" var subString = ["apple"] console.log (str.includes (subString))

convert_to_array = function (sentence) {
     return sentence.trim().split(" ");
};

let ages = convert_to_array ("I'm a programmer in javascript writing script");

function confirmEnding(string) {
let target = "ipt";
    return  (string.substr(-target.length) === target) ? true : false;
}

function mySearchResult() {
return ages.filter(confirmEnding);
}

mySearchResult();

您可以像这样检查并使用过滤器返回匹配单词的数组
