Solution 1:

According to MDN docs for Date.parse() parameter:

dateString

A string representing an RFC2822 or ISO 8601 date (other formats may be used, but results may be unexpected).

Looks like Microsoft simply didn't implement the format you provided. I wouldn't use this format anyway, because it's locale dependent(might just be dd/mm/yyyy or sometimes might also fit mm/dd/yyyy).

An alternative to your solution is to use moment.js. It has a very powerful API for creating/parsing/manipulating dates. I'll show some examples on how you could use it:

//Create an instance with the currentdateandtime
var now = moment();

//Parse the first the first argument using the format specified in the second
var specificTime = moment('5‎/‎12‎/‎2017 09:00 AM', 'DD/MM/YYYY hh:mm a');

//Compares the currentdatewith the one specified
var beforeNow = specificTime.isBefore(now);

It offers a lot more and might help you simplify your code a great deal.

Edit: I rewrote your code using moment.js version 2.18.1 and it looks like this:

functionparseDateCustom(date) {
    returnmoment(date, 'YYYY-MM-DD hh:mm a');
}

var tArray = ["09:00 AM", "05:00 PM"];
var currentDate = moment().format('YYYY-MM-DD') + ' ';
var timeString1 = parseDateCustom(currentDate + tArray[0]);
var timeString2 = parseDateCustom(currentDate + tArray[1]);
var currentTimeString = parseDateCustom(currentDate + "01:18 pm");

if (timeString1.isBefore(currentTimeString) && currentTimeString.isBefore(timeString2)) {
    console.log('Sucess');
} else {
    console.log('Failed');
}
