Convert to: <select name="conversionSelect" id="conversionSelect">

let valueToBeConverted = document.getElementById('value');
let conversionSelect = document.getElementById('conversionSelect');
let convertBtn = document.getElementById('calcBtn');
let outputDisplay = document.getElementById('resultDisplay');
convertBtn.addEventListener('click', calculate);
function calculate(){
let result = 0;
if(conversionSelect.value === 'fahrenheit'){
result = (parseFloat(valueToBeConverted.value) * 9/5) + 32;
outputDisplay.innerHTML = result.toFixed(2);
} else {
result = (parseFloat(valueToBeConverted.value) - 32) * 5/9;
outputDisplay.innerHTML = result.toFixed(2);
}
