Back to home
I’m back home, and I’m loving the early morning rides. Watching the sun rise over green fields, listening to the birds—everything is just so beautiful.

Module in JS
A module is just a file. One script is one module. As simple as that.
- To make
import/exportwork, browsers need<script type="module">. - Modules have several differences:
- Deferred by default.
- Async works on inline scripts.
- To load external scripts from another origin (domain/protocol/port), CORS headers are needed.
- Duplicate external scripts are ignored.
- Modules have their own, local top-level scope and interchange functionality via import/export.
- Modules always use strict.
- Module code is executed only once. Exports are created once and shared between importers.
When we use modules, each module implements the functionality and exports it. Then we use import to directly import it where it’s needed. The browser loads and evaluates the scripts automatically.
In production, people often use bundlers such as Webpack to bundle modules together for performance and other reasons.

Oracle Timestamp
The TIMESTAMP datatype is an extension on the DATE datatype. In addition to the datetime elements of the DATE datatype, the TIMESTAMP datatype holds fractions of a second to a precision between zero and nine decimal places, the default being six. There are also two variants called TIMESTAMP WITH TIME ZONE and TIMESTAMP WITH LOCAL TIME ZONE. As their names imply, these timestamps also store time zone offset information.
