Simple Fixes That Will Instantly Improve Your Code

Let’s be real: bad JavaScript is everywhere. Messy code, unpredictable behavior, and weird errors that make no sense. But here’s the good news—you don’t have to write bad JavaScript.

There are simple habits that can instantly make your code cleaner, faster, and easier to understand. And if you ever get stuck, you can always find expert advice and trending solutions at Javascript Developer Resources - Made by 0x3d.site.

Let’s fix those bad habits today.

1. Stop Using Var—Use Let or Const

var is outdated. It causes unexpected bugs because of function scoping issues. Instead, use:

const name = 'Alice'; // If the value never changes
let age = 25; // If the value might change

This prevents accidental overwrites and hard-to-debug issues.

2. Write Shorter, Clearer Functions

Long, bloated functions are a nightmare. Keep them short:

function getFullName(user) {
  return `${user.firstName} ${user.lastName}`;
}

If a function does too much, break it into smaller functions.

3. Always Use Strict Mode

Strict mode catches silent JavaScript errors and makes debugging easier:

'use strict';

Put it at the top of your files and avoid hard-to-spot mistakes.

4. Use Optional Chaining to Avoid Crashes

Instead of this ugly check:

if (user && user.profile && user.profile.image) {
  console.log(user.profile.image);
}

Just do this:

console.log(user?.profile?.image);

Cleaner, right?

5. Find the Right JavaScript Tools

Stop guessing which libraries and frameworks to use. Just check Trending Repositories to see what developers are actually using.

6. Use Template Literals Instead of String Concatenation

Stop writing clunky code like this:

console.log('Hello, ' + name + '! You are ' + age + ' years old.');

Use template literals:

console.log(`Hello, ${name}! You are ${age} years old.`);

It’s easier to read and less error-prone.

7. Stop Copy-Pasting Code—Use Functions

If you’re writing the same logic multiple times, put it in a function:

function greet(user) {
  return `Hello, ${user.name}!`;
}

This keeps your code DRY (Don’t Repeat Yourself).

8. Use the Right Debugging Tools

Don’t just rely on console.log(). Use console.table() for better debugging:

console.table([{ name: 'Alice', age: 25 }, { name: 'Bob', age: 30 }]);
