Hello to everyone caan someone tell me PLEASE, why something like this doesnt work? for disable the add button if there is not input value .
// a variable that returns true or false if the taskInput.value.lenght is <= than 0
function inputLength() { return taskInput.value.length <= 0; }
//a function that changes the property calling the inputLenghth function.
function disableButton() { addButton.disabled = inputLength(); }
