The following example shows how to display current date and time using Date object in JavaScript. They may tweak results of “artificial tests” compared to “normal usage”, especially when we benchmark something very small, such as how an operator works, or a built-in function. Here is a list of the properties of the Date object along with their description. If we have a UNIX timestamp, we can instantiate a JavaScript Date object by using const timestamp = 1530826365 new Date(timestamp * 1000) unless the timestamp was generated by JS, in which case it’s already in the correct scale.
