JavaScript is a powerful language that can do a lot with very little code. In some cases, the amount of code you need to write doesn't exceed more than a single line, which is why they are known as one-liners. Let's go through 10 essential one liners worth using in

Learn essential one-liners in JavaScript for tasks like capitalizing text, calculating percent, getting a random element, removing duplicates, sorting elements, checking equality, counting occurrences, waiting for a certain time, plucking property from an array of objects, and inserting an element at a certain position.

JavaScript One-Liners to Use in Every Project

9. How to Use the Pluck Property from Array of Objects

10. How to Insert an Element at a Certain Position

To capitalize first letter of every word in the string,
<pre><code class="language-js">const capitalize = (str) =&gt; str.split(&#x27; &#x27;).map(word =&gt; `${word.charAt(0).toUpperCase()}${word.slice(1)}`).join(&#x27; &#x27;)

// Edit: Using reegex
const capitalize = (str) =&gt; {
 return str.replace(/\b[a-z]/gi, char =&gt; char.toUpperCase())
}
</code></pre>

Nice article.
However, JSON.stringify could be problematic when checking objects as you are comparing strings. So if the properties of the object are the same but in different order it won’t be equal and it should.
Example:
<pre><code>const a = { test: 1, hey: 2};
const b = { hey: 2, test: 1};

isEqual(a, b); // returns false
</code></pre>

This is why I keep reading articles I think would have nothing new to me. Never even knew about set and plunk. Plunk is definitely something I am adding to my toolbelt. Thanks.

Good one. I started writing my own methods library <a href="https://github.com/mvdschee/use" target="_blank" rel="noopener nofollow">@mvdschee/use</a>. I keep reusing code snippets like that; it saves a lot of time, not looking up how to do something.
