Why am i getting 'uncaught typeerror: cannot read property 'value' of null' in javascript?


let inputValue = document.getElementById('inputField').value;

This error occurs when an element with the given ID does not exist in the DOM. Always ensure that your JavaScript runs after the DOM has loaded, or check the element's existence before accessing its properties.

document.addEventListener('DOMContentLoaded', function() {
    let inputElem = document.getElementById('inputField');
    if(inputElem) {
        let inputValue = inputElem.value;
