Steps 32

Spreadsheet software typically uses = at the beginning of a cell to indicate a calculation should be used, and spreadsheet functions should be evaluated.

Use the && operator to add a second condition to your if statement that also checks if the first character of value is =.

My solution

const update = event => {
  const element = event.target;
  const value = element.value.replace(/\s/g, "");
  console.log(typeof(value))
  if (!value.includes(element.id)  &&  value.startsWith('=')) {}
}

I don’t know what I am doing wrong here

You need startWith(). Make a simple condition:
First character of value equal to a equal string.

Remove the console log you have added.

console.log(typeof(value))

@hasanzaib1389 it’s not working, I have also tried it with value.charAt(0) and value.startsWith(“=”), getting same error :thinking:

7 
if (!value.includes(element.id) && value.startsWith('=')) {

  }

Suddenly, with same code it started working, and I’m not sure why. Could someone please explain the difference between my previous code and the current code? Thank you!

const update = event => {
  const element = event.target;
  const value = element.value.replace(/\s/g, "");
  console.log(typeof(value))
  if (!value.includes(element.id)  &&  value.startsWith('=')) {}
}

In the previous code, you had a console.log().
