Easy to use JavaScript snippets.

1.- Sort an array.

//strings const names = ["Hello", "How", "Where"]; names.sort(); //['Hello', 'How', 'Where' ] //Numbers const numbers = [5, 1, 87]; numbers.sort((a, b) => { return a - b; }); //[ 1, 5, 87 ] //Sort array based on object: data.sort((a, b) => a.name > b.name ? 1 : -1)

2.- Select a random element.

 const elements = ["Hell", "Can", "Use"]; const getRandomIndex = Math.floor(Math.random() * elements.length); elements[getRandomIndex];
Enter fullscreen mode Exit fullscreen mode

3.- Reverse a string.

const reverseString = (string) => string.split("").reverse().join(""); //Example const stringReverse = reverseString("drag and drop a cover image");
Enter fullscreen mode Exit fullscreen mode

4.- Check if element has class.

 const $elHaveClass = (el, className) => el.classList.contains(className); // Example //Check if the sidebar is open const $elSidebar = document.querySelector(".sidebar"); const isSidebarOpen = $elHaveClass($elSidebar, 'sidebar__open');
Enter fullscreen mode Exit fullscreen mode
