Tis the season! JavaScriptmas is here again! JavaScriptmas is a FREE annual festive coding event hosted by the online coding school Scrimba, consisting of 24 daily coding challenges, prizes, and more!

What is JavaScriptmas?

JavaScriptmas is a festive coding event hosted by Scrimba from December 1st to 24th. Each day, you will get a new JavaScript challenge to help improve your coding skills, and you can win prizes! You can submit each valid challenge solution twice for two chances of winning! Since it's a raffle, it's fair for developers of any coding level, as it doesn't depend on skill.

To submit your challenge solution, click "Submit Solution" to save your work, which will automatically enter you into the Grand Prize draw. For an additional chance to win, click the "Share" button to spread the JavaScriptmas cheer on X and/or LinkedIn—they will select a second lucky winner from the social posts! The more challenges you solve, the better your chances of winning the grand prize, so keep submitting!

On December 24th, they will be choosing two lucky Grand Prize winners who will each receive:

• A 13” MacBook Air M3
• Merch from MDN and Scrimba
• Lifetime Scrimba Pro access

Join the fun and improve your JavaScript skills this holiday season!

Community highlights

In the spirit of the festive holiday season, I enjoy showcasing others' work in the community highlights section of my JavaScriptmas articles! I'll be searching X/Twitter, LinkedIn, and the Scrimba Discord channel for "outstanding" submissions by fellow participants to feature. 🎉

My solutions

As I do every year, I will participate in JavaScriptmas and share my solutions on social media. I will provide links to the Scrims in these coverage articles as I complete the challenges. 💻

Berat (@BeratSakipi)

Berat solved the day one Christmas List challenge and explained in detail how each part of his wishlist variable works. He used JavaScript’s trim, split, filter, join, and toLowerCase to help prepare unique items to enter into the Christmas List, including trimming out troublesome white spaces!

Next, with the wishlist variable ready, Berat uses the JavaScript includes method to check if a duplicate item is already in the list array before adding the new item.

// Function to check item is not duplicate
function checkDuplicate() {
    const itemText = itemInput.value
    // trimming the spaces out of the sentence before checking if it included in the 'listArr' array
    const wishListItem = itemText.trim() // trim the leading and trailing empty spaces
                                 .split(' ') // split every word and possible empty space inside the string into an array of words and spaces
                                 .filter(str => str !== '') // take only the words
                                 .join(' ') // and join them with one space inbetween
                                 .toLowerCase() // transform the word/sentence to lowercase letters
    // Checking if there is an input and if that input value is not included in the 'listArr' array
    if (wishListItem && !listArr.includes(wishListItem)) {
        listArr.push(wishListItem)
        renderList()
    }
}

Berat also solved the delete button stretch goal, as you can see in the code block below. Great job, Berat!

// Function to add an item to the shopping list
function renderList() {
    shoppingList.innerHTML = ''
    listArr.forEach((gift, index) => {
        const listItem = document.createElement('li')
        listItem.textContent = gift
        
        const deleteItemBtn = document.createElement('button')
        deleteItemBtn.textContent = 'Delete Item'
        deleteItemBtn.classList.add('delete-gift-btn')
        deleteItemBtn.id = `delete-gift-btn`
        
        const giftContainer = document.createElement('div')
        giftContainer.classList.add('gift-container')
        
        deleteItemBtn.addEventListener('click', () => {
            listArr.splice(index, 1)
            renderList()
        })
        
        giftContainer.appendChild(listItem)
        giftContainer.appendChild(deleteItemBtn)
        shoppingList.appendChild(giftContainer)
    })
    itemInput.value = ''; // Clear the input field
}

For the day two challenge, Lynjai Jimenez created a beautiful “ugly calendar!“ She completed the stretch goal of clicking each box to reveal an opened image and included captivating animations!

Lynjai also turned the calendar into a countdown! Each date box clicked brings you one day closer to JavaScriptmas! Outstanding work, Lynjai Jimenez!

Features:

• User can click each day to open
• UI has been updated with Christmas colors
• Added countdown to JavaScriptmas
• The 24th day changes the background image
• User can unclick the current clicked date if needed
