Hi all,

I'd be documenting the 30 days challenge of JavaScript I just joined, though the challenge is now at day 7 but it's never late.

PS: I'm just way below average JavaScript user with no experience. Hence, most codes here will not be too refined or optimized. I'd appreciate all suggestions to make my codes more optimized.

Day 1

Array Sum

Create a function that calculate the sum of an array. The function should receive an array as it's parameter and return the sum of the numbers in that array.

For example:

sumOfArray([1, 5, 4]) // returns 10;



sumOfArray([1, 2, -3, 5]) // returns 5;

Array Sum

Create a function that calculate the sum of an array. The function should receive an array as it's parameter and return the sum of the numbers in that array.

For example:

sumOfArray([1, 5, 4]) // returns 10;



sumOfArray([1, 2, -3, 5]) // returns 5;

// Day 1 Solution


const sumArray = function (Array) {
let sum = 0;
for (let i = 0; i < Array.length; i++) {
sum += Array[i];
}
console.log(sum);
}
const arrayToAdd = [1, 2, 3 , 8]; //Output 14
const arrayToAdd1 = [9, 19, 73] //101
sumArray(arrayToAdd);
sumArray(arrayToAdd1)

Day 2

FizzBuzz

Create a function that takes an integer as its input. The function should print all numbers from 1 to n but follow these rules as well:

- If the number is divisible by 3, print Fizz in its place

- If the number is divisible by 5, print Buzz in its place

- If divisible by both 3 and 5, print FizzBuzz

For example:

Input => 3

Output => 1 2 Fizz

Input => 15

Output => 1 2 Fizz 4 Buzz Fizz 7 8 Fizz Buzz 11 Fizz 13 14 FizzBuzz

// Day 2 Solution
// Fizz, Buzz, FizzBuzz

function counter (numberInput) {

for (let i = 0; i <= numberInput; i++) {
if (i % 3 === 0 && i % 5 === 0) {
console.log('FizzBuzz');
} else if ( i % 5 === 0) {
console.log('Buzz');
} else if (i % 3 === 0) {
console.log('Fizz');
} else {
console.log(i);
}

}

}

counter(15)

Are you new to JavaScript?

Kind of.
But;
I've got knowledge of how things work.
As I've done some basic projects with it though.

I hope u ar not copying ans from d web, some spying things.

Any way you are doing good.

I was just wondering why you didn't use the reduce function for the Array sum

Lol. I'm not copying answers from the internet BUT whenever I'm stuck, I look up things but I do not copy and dump codes.

I feel looking things up on stackoverflow and other platform is part of learning process and programming. BUT I do not copy and dump codes

Thank you so much.

You're also welcome to drop any solution even to the ones I've done. If there's a better way of doing things.

Deicide:

Oh! You're right. I never thought of it.
But then, if I had thought of it. I'd have avoided it because the challenge is to avoid built in method to get some things done.

Like in Day 7. Which is today's task. It was asked to sort an unorganized array without using the sort() method.

I think you are doing well keep up the thread, you will learn about reduce and the rest as time goes on, I think everyone learning should create a thread to track their progress.

Hi qtguru.
What do you think about zapier and Zoho on upwork?

Biggerbros234:

Hi qtguru.
What do you think about zapier and Zoho on upwork?

They exist on Upworks, if you use them you have to search for gigs using those keywords, infact more platforms are jumping up these days.

Another is Webflow, there are so many Webflow gigs.

qtguru:
I think you are doing well keep up the thread, you will learn about reduce and the rest as time goes on, I think everyone learning should create a thread to track their progress.

Wow! Thanks for dropping by qtguru.
And thanks for the compliment too.

Yeah, you're right! Like what I've learned in the few days I started this challenge is really amazing. Even things I know before are better understood solving some questions of the challenge.

Day 3

FizzBuzz Pro Max
Write a function that takes an array of numbers and returns an array that contains arrays where each array contains the output that would have been spat out if the FizzBuzz function was called on the number

[4, 10, 6] => [[1,2,Fizz,4], [1,2,Fizz,4,Buzz,Fizz,7,8,Fizz,Buzz], [1,2,Fizz,4,Buzz,Fizz]]

// Day 3 Solution

function takesArray (theArray) {
 let arrTakes = [];
    for (let element of theArray) {
        for (let i = 0; i <= element; i++) {
            if (i === 0) {
                arrTakes.push()
            }
            else if (i % 5 === 0 && i % 3 === 0) {
                arrTakes.push('FizzBuzz');
                } else if ( i % 5 === 0) {
                arrTakes.push('Buzz');
                } else if (i % 3 === 0) {
                    arrTakes.push('Fizz');
                } else {
                arrTakes.push(i);
                }
        }
    }
    const outputArray = console.log([arrTakes]);
}

takesArray([4,15,6])


PS: This code is not as optimized as I wanted it to be. The output gave the required results but it's not as packed as the challenge require.


I'll appreciate if anyone can post a more optimized solution or give a pointer to how things can be done perfectly. Thank you

Day 4

Create a function that takes in an array of objects containing properties: name, age and level. It should return an array of strings where each string is a concatenation of all values contained in the object separated by a slash

For example:

[{name: ‘Seun’, age: 23, level: ‘100 level’}] => Your function => [‘Seun/23/100 level’]


[{name: ‘Seern’, age: 23, level: ‘500 level’}, {name:’BBBgh’, age:’twenty three’, level: ‘year 1’}] => Your function => [‘Seern/23/500 level’,’BBBgh/twenty three/year 1’]

// Day 4 Solution

        const theIteration = (`${objects[i].name}/${objects[i].age}/${objects[i].level}`);
        emptyArray.push(theIteration);

}, {
    name : 'BBBgh',
    age : 'twenty three',
    level : 'year 1'
}]

callArrayOfObject(arrayOfObject);
callArrayOfObject(arrayOfObject1);

Day 5

Create a function that does the opposite of what yesterday’s function did. It takes the output of the function and returns the input.

Therefore, your function should take an array of strings containing the name, age and level values separated by a slash. Your function should return an array of objects that have the name, class and level keys with their corresponding values.

For example:

[‘Seun/23/100 level’] => Your function => [{name: ‘Seun’, age: 23, level: ‘100 level’}]


[‘Seern/23/500 level’,’BBBgh/twenty three/year 1’] => Your function => [{name: ‘Seern’, age: 23, level: ‘500 level’}, {name:’BBBgh’, age:’twenty three’, level: ‘year 1’}]

Day 6

Create a function that takes 2 inputs: an array of numbers and a target number. Your function should return the indices of the numbers that add up to form the target number. If no two numbers make up the target number, return -1, -1

NB: All numbers in the array can only be used once to add up to the target.

NB2: The indices should be returned in an array

For example:

[1,9,4,5,3, 0] , 10 => Your function => [0,1]



[2,5,9,6,1,53, 45], 47 => Your function => [0,6]



[4,9,3,5,0,14,10], 100 => Your function => [-1, -1]

Nice!

All this stuffs na d question just dey confusing.

Now I gt the question, find the index position of two numbers in the array that will add up to make the target number.

U dey try.

Good speed!

Thank you boss!

Yeah, the questions are mostly confusing sometimes. I sometimes read over and over then sit over it to understand.

Like when I first read this particular question. My mind went to mathematics indices until I figured it's plural of index that's being mentioned.
