Remove last 3 characters of string or number in javascript

I'm trying to remove last 3 zeroes here: 1437203995000

How do I do this in JavaScript? I'm generating the numbers from new date() function.

Here is an approach using str.slice(0, -n). Where n is the number of characters you want to truncate.

var str = 1437203995000; str = str.toString(); console.log("Original data: ",str); str = str.slice(0, -3); str = parseInt(str); console.log("After truncate: ",str);

Remove last 3 characters of a string

var str = '1437203995000'; str = str.substring(0, str.length-3); // '1437203995' 

Remove last 3 digits of a number

var a = 1437203995000; a = (a-(a%1000))/1000; // a = 1437203995 

you just need to divide the Date Time stamp by 1000 like:

var a = 1437203995000; a = (a)/1000;
