const calcMean = (array) => {
let sum = new Number();
for (let i = 0; i < array.length; i++) {
sum += array[i];
}
return sum / array.length;
};
console.log(calcMean([10, 20, 30]));

[CodeWithAyan]

my solution: let calMean = (arr) => {
if (arr.length === 0) return 0;
return avg = arr.reduce((acc, curVal) => acc + curVal) / arr.length;
};
console.log(calMean([1, 2, 3, 4, 5]));

[Goutamwaghe]

function calcMean(arr) {
if (arr.length === 0) return 0;
const sum = arr.reduce((pv, cv) => {
return pv + cv;
}, 0);
return sum / arr.length;
}
console.log(calcMean([1, 2, 3, 4, 5, 6]));
console.log(calcMean([]));
console.log(calcMean([-1, 0, 1]));

[mahuKhaLnaYak]

function findMean(arr) {
let middleVal = Math.floor(arr.length / 2)
if (arr.length === 0) {
console.log("The array is empty")
} else {
console.log("The mean in "+arr+" is "+ arr[middleVal])
}

}
findMean([1, 2, 3, 4, 5, 6])

[Tarun-zvzf]

const meanCalculator = (numarray)=> {
return (numarray.reduce((acc, curr) => acc + (+curr), 0))/numarray.length
}

[SurajKumar-knko]

const calculateMean = (arr) => {
if(arr.length===0)
return 0
return arr.reduce((accume, currValue)=>{
return accume+currValue
}, 0)/arr.length
}

[SahilSoni-zcub]

let mean = [10, 20, 30];
const calculateMean = () => {
let half = mean.length;
mean = mean.reduce((acc, cur) => acc + cur, 0);
let meanvale = mean / half;
console.log(meanvale);
};

calculateMean();

[Chirag]

let arr = [1, 2, 3, 4, 5];
console.log(mean(arr));
function mean(arr){
if(arr.length == 0){
return 0;
}
let i = 0;
let sum = 0;
let n = arr.length;
while(i<n){
sum += arr[i];
i++;
}
return sum/n;
}

[syedabdullah]

// Write a function to find the average of a set of numbers

const averageOf = (arr) => {
let length = arr.length;
arr = arr.reduce((acc, curr) => {
return acc + curr;
}, 0);
let result = arr / length;
return result;
};

console.log(averageOf([1, 2, 3, 5]));
console.log(averageOf([1, 2, 3]));

JavaScript Challenge 100/21 days is Completed👍

[nitishsingh]

const calculateMean = (arr) => {
if (arr.length === 0) return 0;
return arr.reduce((a, c) => a + c, 0) / arr.length;
};

[bhaviksuiya]

const Mean = (arr) => {
return (arr.reduce((acc, cur) => (acc += cur), 0)/ arr.length);
};

[Yardss]

Your explanation is very understandable 😄❤

[vikrambais]

let arr = [-1, 0, 1]

function findMean(arr){
if(arr.length === 0){
return 0
}
let sum = 0
arr.map((num)=>{
sum += num

})
return sum/arr.length
}


let value = findMean(arr)
console.log(value)

[sarfrazshah]

const calculateMean = (arr) => {
if (arr.length === 0) {
return 0;
}
let total = 0;
for (let i = 0; i < arr.length; i++) {
total = total + arr[i];
}
if (total === 0) {
return 0;
}
return total / arr.length;
}

[kevalvala-unry]

const calculateMean = (arr) => {
if (arr.length === 0) {
return 0;
}
else {
let sum = 0;
for (i = 0; i < arr.length; i++) {
sum = sum + arr[i];
}
let mean = sum / arr.length;
return mean;
}
return;
}


console.log('Output is here: ', calculateMean([1, 2, 3, 4, 5])); // output: 3

[ilhanahmed]

function Mean(nums) {
if (nums.length === 0) return 0;
return (
nums.reduce((acc, curr) => {
return acc + curr;
}, 0) / nums.length
);
}

console.log(Mean([1, 2, 3, 4, 5]));
console.log(Mean([10, 20, 30]));
console.log(Mean([-1, 0, 1]));
console.log(Mean([]));

this video does not deserve to be 20th day task. give us some good task that is worth applying mind and time.
