இந்த reduce method என்னோட பொறுமைய ரொம்ப reduce பண்ணிடுச்சி mam 😢

[reubenprasanth]

Bing Ai thunai 😅🙏

let arr = [1, 2, 3, 4, 5, 1, 2, 3];
let uniqueArr = arr.reduce(function (acc, val) {
if (acc.indexOf(val) === -1) {
acc.push(val);
}
return acc;
}, []);
console.log(uniqueArr); // Output: [1, 2, 3, 4, 5]

In this example code snippet, we have an array arr with some duplicate values. We use the reduce() method to iterate over each element of the array and check if it already exists in the accumulator array acc. If it doesn’t exist in the accumulator array acc, we push it to the accumulator array acc. Finally, we return the accumulator array acc which contains only unique values.

Hi mam, inside of call back when you call the method, we no need to pass argument?


However the convert function is declared with parameter...

Hi sister, do you have plans on creating tutorials for Kotlin in future :) ?

let inputs = [6, -5, 7, -2, 4, 6, -1]
let positiveNumbs =
function findPositiveNumbs(val, index) {
return val = val > 0
}
console.log(positiveNumbs); // 6 7 4 6

let sumOfPositiveNumbs = positiveNumbs.reduce(sum);
function sum(val, el) {
return val = val + el
}
// 23

[sunilgeorge]

Find the sum of positive numbers only:

const arr = [6, -5, 7, -2, 4, 6, -1]

const result = arr.filter(x => x > -1).reduce((accumulator, currentValue) => {
return accumulator+currentValue
}, 0)
console.log(result); // 23

[sunilgeorge]

Abbreviate by gathering first letter of each word:

const str = "Robert Andrew George"

const arr = str.split(' ')
const result = arr.reduce((accumulator, currentVal) => {
accumulator += currentVal.charAt(0)
// accumulator += currentVal.slice(0, 1)
// accumulator += [...currentVal][0]
// accumulator += Array.from(currentVal)[0]
return accumulator
}, '')

console.log(result);
