Whether the query string already exists

On a website to cast a resume, the company has more than one to check, compare which companies have been cast, a little time,

Write a small query to find out if the ready delivery company is in the cast list:

<input type= "text" placeholder= "Please enter company name" id= "Companies"/>

<script type= "Text/javascript" >

function S (FN) {
Return fn.tostring (). Split (' \ n '). Slice (1,-1). Join (' \ n ') + ' \ n ';
}

var str=s (function () {

What doing}),
Arr=str.replace (/^\s+|\s+$/g, "). Replace (/\S+/GM," "). Split (" ");

var companyinput=document.queryselector ("#company");
Companyinput.onblur=function () {
var txt=companyinput.value.replace (/^\s+|\s+$/g, "). Replace (/\S+/GM," "),
Len=arr.length,
Max=math.ceil (LEN/2);

Console.time ("Timmer1");
for (var i=0; i<len; i++) {
if (arr[i]==txt) {
Console.log (TXT);
Break
}
}
Console.timeend ("Timmer1");

Console.time ("Timmer");
for (var i=0;i<max; i++) {
if (arr[len-i]==txt| | Arr[i]==txt) {
Console.log (TXT);
Break
}
}
Console.timeend ("Timmer");
}

Would like to make the query a little faster, take half the length, the end of the same time contrast, test down, so slower
