Let’s be real—coding can sometimes feel like a never-ending marathon of the same boring tasks. You write, debug, tweak, repeat. But what if I told you there’s a secret stash of tiny code snippets that could literally cut your work in half and make your life 10x easier?
Over the years, I’ve built up my personal toolkit of code snippets that I pull out every single time I start a new project. They’re simple, they’re powerful, and best of all—they save me tons of time and headaches.
Here’s the deal: I’m sharing my top 10 snippets that are like little magic shortcuts in your code. Bookmark this, share it, and thank me later.
1. Debounce: The “Stop Spamming Me!” Button for Events
Ever noticed how when you type or resize a window, your function fires off like crazy? Debounce lets you tell your code, “Chill, wait a sec before running that again.”
javascript
Copy
Edit
function debounce(func, wait) {
let timeout;
return function(...args) {
clearTimeout(timeout);
timeout = setTimeout(() => func.apply(this, args), wait);
};
}
Say goodbye to sluggish UIs!
2. Deep Clone: Copy Stuff Without Messing It Up
Want a clone of your object that won’t break if you change it? This snippet is the magic wand for that.
javascript
Copy
Edit
const deepClone = obj => JSON.parse(JSON.stringify(obj));
No more accidental mutations ruining your day.
3. Fetch with Timeout: Because Nobody Likes Waiting Forever
Network requests can hang forever if the server’s slow. This snippet makes sure you bail after a timeout and handle the error gracefully.
javascript
Copy
Edit
function fetchWithTimeout(url, timeout = 5000) {
return Promise.race([
fetch(url),
new Promise((_, reject) => setTimeout(() => reject(new Error('Timeout')), timeout))
]);
}
Stay in control of your app’s speed!
4. Capitalize First Letter: Make Text Look Nice in One Line
Quick and dirty text beautifier.
javascript
Copy
Edit
const capitalize = str => str.charAt(0).toUpperCase() + str.slice(1);
Perfect for UI polish.
5. Unique Array Elements: Bye-Bye Duplicates
Got a messy array? Clean it up instantly.
javascript
Copy
Edit
const unique = arr => [...new Set(arr)];
Trust me, this one’s a life saver.
6. Format Date to YYYY-MM-DD: Keep Dates Consistent AF
Don’t mess with date formatting ever again.
javascript
Copy
Edit
const formatDate = date => date.toISOString().split('T')[0];
Dates made simple.
7. Throttle: Like Debounce’s Cool Older Sibling
Throttle makes sure your function runs at most every X milliseconds. Great for scroll events and such.
javascript
Copy
Edit
function throttle(func, limit) {
let lastFunc;
let lastRan;
return function(...args) {
if (!lastRan) {
func.apply(this, args);
lastRan = Date.now();
} else {
clearTimeout(lastFunc);
lastFunc = setTimeout(() => {
if ((Date.now() - lastRan) >= limit) {
func.apply(this, args);
lastRan = Date.now();
}
}, limit - (Date.now() - lastRan));
}
};
}
Keep it smooth and snappy.
8. Check if Object is Empty: Quick Validation Hack
Sometimes you just need to know if an object’s empty or not. Simple and neat.
javascript
Copy
Edit
const isEmptyObject = obj => Object.keys(obj).length === 0;
9. Get Query Parameters from URL: Parse Like a Pro
Grab query params effortlessly.
javascript
Copy
Edit
const getQueryParams = url => {
const params = {};
new URL(url).searchParams.forEach((value, key) => {
params[key] = value;
});
return params;
};
Perfect for any web app.
10. Random Integer in Range: Because Random Is Fun
Generate random numbers like a boss.
javascript
Copy
Edit
const randomInt = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min;
Use it for games, animations, or fun experiments.
