</h2>

<p>HTML <canvas> is an HTML element with the tag <canvas> that is used to draw graphics in two or three dimension via Javascript. The <canvas> is a wrapper that can be manipulated by javascript to create texts, images, shapes, animations to create visually appealing and interactive elements.</p>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467309376509.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."></p>

<p>The use of <canvas> is available in all browsers and devices which gives the developers the flexibility to create amazing graphics.  </p>

<h4>
  
  
  Use Cases of HTML <canvas>
</h4>

<ul>
<li>Drawing shapes and lines: It can draw shapes, patterns and lines including adding of colors and gradients to the objects.</li>
<li>Animation and interaction: The objects created by <canvas> can be animated and also user interactions</li>
<li>Images Manipulation: This can used to resizing or cropping images.</li>
<li>Game graphics: It is also used by game developer to create beautiful game user interfaces</li>
<li>Data visualization:  It is for the creation of graphs and charts.</li>
</ul>

  ?<strong>Get Started</strong>
</h2>

<p>The HTML <canvas> is used in the HTML file and can be manipulated internally in the script tag or externally in the javascript file. Without this, the canvas object will not be displayed. <br>
First we have to create an index.html file and include the <canvas>wrapper for the object to be created.<br>

<p>Then we add a script tag so we can define the behavior of the object.<br>
</p>

<pre class="brush:php;toolbar:false"><!doctype html>
   <html lang="en">
     <head>
       <meta charset="UTF-8" />

     <body>
       <canvas>



<p>Wowu !!! We get the output.</p>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467309470040.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."></p>

<p>Looking at the structure of the code. We define canvas wrapper having an id attribute, this is can only be done by id and not class because of uniqueness which is used to reference the canvas with the id name.<br>
To access this we need to retrieve the node created in the Document Object Model(DOM) by using the getElementById("myCanvas") and have access to it using the getContext("2d") method.</p>

<p>This method make us to have access to different drawing methods like</p>

</pre></pre>
<ul>
<li>
fillRect(x, y, width, height): This method is to draw a filled rectangle at a position(x, y) with a specified width and height.</li>
<li>
fillStyle = colorName: It is a property to set the color for the object. It could be a colorname, RGB or hex code for the object.</li>
</ul>

<p>Other methods are:</p>

<ul>
<li>
strokeRect(x, y, width, height): This method to to make a outline stroke on the rectangle, this may be used independently or combined with fillStyle and fillRect(x, y, width, height).</li>
<li>
clearRect(x, y, width, height): to clear the rectangle by making it transparent.</li>
</ul>

<h2>
  
  
  ? <strong>Drawing basics</strong>
</h2>

<p>Different shapes and lines can be drawn using some specific methods depending on the object.</p>
<h4>
  
  
  1. Path:
</h4>

<p>Examples are line, wavy line, zigzag e.t.c</p>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467309649925.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."></p>

<p>For creating a line, the following method needs to be set up:</p>

<ul>
<li>
beginPath(): This method is to start a new path for a drawing.</li>
<li>
moveTo(x, y): This is to move the drawing to the specified points.</li>
<li>
lineTo(x, y): This is to draw from the current position to the specified points.</li>
<li>
stroke(): This is to draw the line.</li>
</ul>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467309776138.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."></p>
<h4>
  
  
  2.   Rectangle and Square
</h4>

<ul>
<li>Rectangle</li>
</ul>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467309977240.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."></p>

<ul>
<li>Square </li>
</ul>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467310125861.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."></p>

<p>These following methods are used in creating a rectangle or square:</p>

<ul>
<li>
fillRect: this method is for create rectangle and square only.</li>
<li>
clearRect(x, y, width, height): this method is to clear rectangle hence making it transparent.</li>
<li>
strokeRect(x, y, width, height): is used to create an outline rectangle or square.</li>
<li>
fillStyle: this is used to fill the container of the rectangle or square.</li>
<li>
strokeStyle: this method is for add stroke color to an outline rectangle.</li>
<li>
roundRect(x, y, width, height, radii): this method is for creating round border rectangle.</li>
</ul>
<h4>
  
  
  3. Circle
</h4>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467310240234.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."><br>
 These following methods are used in creating a circle:</p>

<ul>
<li>
beginPath(): this method to begin a path.</li>
<li>
arc(x, y, radius, startAngle, endAngle, anticlockwise): this is for to create circle where x and y is for center coordinate of the center, radius is the radius of the circle, startAngle and endAngle which is an angle for the circle.</li>
</ul>
<h4>
  
  
  4. Polygon
</h4>

<p>To create a polygon, you need to determine the sides of the shape, it could be a triangle(3 sides), pentagon (5 sides), hexagon(6 sides) or decagon  (10 sides).</p>

<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173467310482546.jpg" class="lazy" alt="HTML Canvas Made Simple: A Guide for Beginners."></p>

<p>These following methods are used in creating a circle:</p>

<ul>
<li>
beginPath(): this method is to create a new shape.</li>
<li>
closePath(): this method is to end the shape.</li>
<li>
cx: its value for the center of x co-ordinates.</li>
<li>
cy: its value specifies the center for y co-ordinates.</li>
<li>
radius: radius of the shape.</li>
</ul>

<p>To get the angle, you have to calculate with this formula by dividing the circle into two;<br>
</p>

<pre class="brush:php;toolbar:false">angle = 2π/ n
</pre>



<p>where π is 3.14; n is the number of sides. You also have to minus π/2 to get the position of the shape top to bottom.<br>

								<p class="Articlelist_txts_p">The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.</p>

								<p class="Articlelist_txts_p">Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.</p>

								<p class="Articlelist_txts_p">If JavaScript applications load slowly and have poor performance, the problem is that the payload is too large. Solutions include: 1. Use code splitting (CodeSplitting), split the large bundle into multiple small files through React.lazy() or build tools, and load it as needed to reduce the first download; 2. Remove unused code (TreeShaking), use the ES6 module mechanism to clear "dead code" to ensure that the introduced libraries support this feature; 3. Compress and merge resource files, enable Gzip/Brotli and Terser to compress JS, reasonably merge files and optimize static resources; 4. Replace heavy-duty dependencies and choose lightweight libraries such as day.js and fetch</p>

								<p class="Articlelist_txts_p">The main difference between ES module and CommonJS is the loading method and usage scenario. 1.CommonJS is synchronously loaded, suitable for Node.js server-side environment; 2.ES module is asynchronously loaded, suitable for network environments such as browsers; 3. Syntax, ES module uses import/export and must be located in the top-level scope, while CommonJS uses require/module.exports, which can be called dynamically at runtime; 4.CommonJS is widely used in old versions of Node.js and libraries that rely on it such as Express, while ES modules are suitable for modern front-end frameworks and Node.jsv14; 5. Although it can be mixed, it can easily cause problems.</p>
