Learn JS in 2 minutes - Part 2 What are rest and spread operators? 🔺Definitions * Rest: The rest operator allows you to represent an indefinite number of arguments as an array. * Spread: the spread operator does the opposite - it "spreads" the elements of an array (or any iterable) out. 🔺Examples Here is how we use rest operator for infinite number of arguments: function sum(...args) { return args.reduce((total, current) => total + current, 0); } ✅ and the result will be: console.log(sum(1, 2, 3, 4)); // 10 and Here's how you can use spread to combine arrays: const arr1 = [1, 2, 3]; const arr2 = [4, 5, 6]; const combined = [...arr1, ...arr2]; ✅ and the result will be: console.log(combined); // [1, 2, 3, 4, 5, 6]

Removing duplicate elements from an integer array without using new array const arr = [1,2,3,5,3,1,9] function f(arr){   arr.forEach((item,i)=>{        for(let j=i+1;j<arr.length;j++ ){          if(item===arr[j]){            arr.splice(j,1)          }        }   }) return arr }  const fun= f(arr) console.log("Try programiz.pro",fun); 🤐🤐🤐

Below code output, please write in comment box. function rotateArray(arr, k) {  const n = arr.length;  k = k % n; // In case k is greater than array length  return [...arr.slice(n - k), ...arr.slice(0, n - k)]; } const array = [1, 2, 3, 4, 5]; const rotatedArray = rotateArray(array, 2); console.log(rotatedArray);

to write a program to convert a string (eg: "My name is Murari Gupta" to =:> "Gupta Murari is name My" && =:> "atpuG iraruM si eman yM") let names = "My name is Murari Gupta"; let arr1 = names.split(" "); let arr11 = arr1.reverse() console.log(arr11.join(" ")) let arr2 = names.split("") let arr22 = arr2.reverse() console.log(arr22.join(""))

well well well, look who finally got a new version https://lnkd.in/d_rdyCjY

This blog post discusses how errors are handled in OpenTelemetry.

Okay, listen. If you're going to fetch in useEffect(...), you should at least make sure that you're handling: - Loading states - Error handling (rejections & HTTP error codes) - Race conditions & cancellation This isn't over-engineering. It's the minimum code to prevent bugs.
