Learn Form Validation by Building a Calorie Counter - Step 32

I tried a lot to get out of this step but all in vain
help to solve that
Number inputs only allow the e to occur between two digits. To match any number, you can use the character class [0-9]. This will match any digit between 0 and 9.

Add this character class before and after e in your pattern.

function isInvalidInput(str) {
  const regex = /[0-9]/i;
}
