Zoom in Image.html

ImPisces 𠮷 🕉️ — Sat, 05 Jun 2021 21:23:26 +0000

In this post, we'll see how to create an image zoomer which allows users to zoom an image using a range slider. Here is the structure of the elements:

Prepare the image container
The image will be displayed at the center of its container. In case users zoom in the image to the level which makes the image bigger than its container, then we'll hide the outside parts.

Having that imagination, the container could be styled as below:

Calculate the initial scale
Initially, we want the image to be fit within its container. To do that, we clone the image and handle the load event to determine the size of image:

The initial scale can be determined based on the widths of container and image:

Now we scale the image to that value by setting the transform style:

Create the range slider
You can take a look at the Create a range slider post for more details. Initially, we want to set the slider range based on the scale calculated in the previous section.

First, we define the minimum and maximum scales and calculate the range step:

It's also possible to set the lower and upper values based on the initial scale. I set constant values to make this post simple.

The slider can update the value via the width of left part:

Scale the image when sliding the range
In the previous section, we set the initial value for the slider based on the scale. It's the time to do the other part, update the scale based on the slider's value.

It happens when user drags the knob:

Enjoy the demo!

Influences and Nature of the Language

ImPisces 𠮷 🕉️ — Fri, 04 Jun 2021 17:52:19 +0000

JavaScript’s creator, Brendan Eich, had no choice but to create the language very quickly (or other, worse technologies would have been adopted by Netscape). He borrowed from several programming languages: Java (syntax, primitive values versus objects),
Scheme and AWK (first-class functions), Self (prototypal inheritance), and Perl and Python (strings, arrays, and regular expressions).

JavaScript did not have exception handling until ECMAScript 3, which explains why the language so often automatically converts values and so often fails silently: it initially couldn’t throw exceptions.

On one hand, JavaScript has quirks and is missing quite a bit of functionality (blockscoped variables, modules, support for subclassing, etc.). On the other hand, it has several powerful features that allow you to work around these problems. In other languages, you learn language features. In JavaScript, you often learn patterns instead. Given its influences, it is no surprise that JavaScript enables a programming style that is a mixture of functional programming (higher-order functions; built-in map, reduce, etc.) and object-oriented programming (objects, inheritance).
