JavaScript Snippet – 1: Quick ToDo List

Organize your day with a simple, interactive ToDo list: You might not do that every day but there is no harm in being nerdy JavaScript developer.

let toDoList = [];

function addToDo(task) {
    toDoList.push(task);
    console.log(`Added task: ${task}`);
}

    console.log("Your ToDo List:");
    toDoList.forEach((task, index) => {
        console.log(`${index + 1}: ${task}`);
    });
}

// Example usage
addToDo("Learn JavaScript");
addToDo("Read a book");
viewToDoList();

JavaScript Snippets – 2: Fetch and Display API Data

Easily fetch and display data from any API: I’m sure you will be using this.

async function fetchData(url) {
    try {
        let response = await fetch(url);
        let data = await response.json();
        console.log(data);
    } catch (error) {
        console.error("Fetching data failed:", error);
    }
}

// Example usage
fetchData("https://jsonplaceholder.typicode.com/todos/1");

JavaScript Snippet – 3: Basic Countdown Timer

A simple timer to help you manage time effectively: A fun way to count in loops.

function startCountdown(seconds) {
    let counter = seconds;

    const interval = setInterval(() => {
        console.log(counter);
        counter--;

        if (counter < 0) {
            clearInterval(interval);
            console.log("Countdown finished!");
        }
    }, 1000);
}

// Example usage
startCountdown(10);

JavaScript Snippets – 4: Simple Email Validator

Quickly validate email formats in user inputs: I love this and I am sure you will too.

function isValidEmail(email) {
    const emailRegex = /^\w+([.-]?\w+)*@\w+([.-]?\w+)*(\.\w{2,3})+$/;
    return emailRegex.test(email);
}

// Example usage
console.log(isValidEmail("example@email.com")); // true
console.log(isValidEmail("example.com")); // false

JavaScript Snippet – 5: Toggle Element Visibility

Toggle the visibility of elements on your webpage:

function toggleVisibility(elementId) {
    const element = document.getElementById(elementId);
    if (element.style.display === "none") {
        element.style.display = "block";
    } else {
        element.style.display = "none";
    }
}

// Example usage in HTML: <div id="myDiv">Content</div>
toggleVisibility("myDiv");
