Boost Your Angular Skills with These Mind-Blowing Tips and Tricks
<p>Welcome to the world of Angular, where powerful web applications come to life! If you’re already familiar with this incredible framework, you might think you’ve seen it all. However, in this article, I will tell you about some hidden treasures that will take your Angular skills to a whole new level.</p>
<p>Let’s go through the top 10 lesser-known tips and tricks for Angular:</p>
<ol>
<li><strong>Using trackBy with ngFor:</strong><br />
<strong>ngFor</strong> is used to loop over a list of items and display them. When this list changes, Angular needs to update the DOM accordingly. <strong>trackBy</strong> helps Angular identify unique items, making updates more efficient.</li>
</ol>
<pre>
<ul>
<li *ngFor=”let item of items; trackBy: trackById”>{{ item.name }}</li>
</ul></pre>
<pre>
// In your component
trackById(index: number, item: any): number {
return item.id; // Use a unique identifier for each item (e.g., 'id')
}</pre>
<p><strong>2.</strong> <strong>Lazy Loading of Modules: </strong>Lazy loading loads specific parts of your app only when needed, reducing the initial loading time.</p>
