Top 3 Simple JavaScript Techniques for Efficient Coding
Written on
Chapter 1: Introduction to JavaScript
JavaScript stands out as a favored choice among programmers, frequently topping the list of the most popular programming languages. Despite its accessibility, JavaScript can present challenges at times. Here, we will explore three handy shortcuts to enhance your coding experience.
Section 1.1: Streamline Your Conditional Statements
If you're accustomed to using "if-else" statements frequently in your code, consider leveraging the ternary operator to condense your syntax. This approach not only simplifies your code but also enhances readability, provided that the logic remains straightforward.
For instance, instead of writing:
const a = 101;
let x;
if (a > 100) {
x = "Hurray! We've crossed the 100 mark.";
} else {
x = "Not yet 100.";
}
You can achieve the same result with a ternary operator:
const x = a > 100 ? "Hurray! We've crossed the 100 mark." : "Not yet 100.";
Section 1.2: Utilizing Array Filters
If you're unfamiliar with array filters, they are essential for creating new arrays composed of elements that satisfy a specified condition. Unlike traditional methods, array filters do not alter the original array; instead, they generate a new array containing only the relevant elements.
Consider the following example:
const appleCount = [1, 2, 3, 4, 5, 6, 7, 8];
const healthyApples = appleCount.filter(checkApple);
function checkApple(count) {
return count >= 3;
}
This code snippet will generate an array of apples that meet the health criteria.

Section 2.1: Implementing Caching
Another efficient strategy is to cache frequently used variables. This technique can significantly boost performance by reducing loading times. By storing values that are accessed repeatedly, you can conserve both time and resources, ultimately speeding up your tasks.
These shortcuts can prove invaluable in your JavaScript programming endeavors. Wishing you the best on your coding journey!
