I want to check if time and day is same when I click to add these paragraphs into the array, If time and day is same then also prevent adding items into an array. Can Anyone help me please.Thanks
window.addEventListener("load", function() {
var test = [];
[...document.querySelectorAll(".container p")].forEach(function(para) {
para.addEventListener("click", function(e) {
var text = e.currentTarget.textContent;
if (test.indexOf(text) === -1)
{
test.push(text);
}
console.log(test)
})
})
}) <div class="container">

querySelectorAll()into an Array is good practice for ensuring that older browsers that don't support.forEach()on node lists will be able to execute the.forEach(). However, those same browsers that don't support.forEach()on node lists also don't support the spread operator..., so that part of the statement will fail. The correct approach for backwards compatibility isArray.prototype.slice.call(collection here).forEach(...).
