Hi There,

You are asked to complete the code to create a function expression that creates an anonymous function using the arrow syntax with 2 parameters : string & letter.

It looks like this

const something = ( ) => {

}

Now I will give you guides on how to create an anonymous function using arrow syntax.

  1. Parenthesis cannot be omitted if the function doesn't take any parameters
  2. If the function accepts one parameter you can ommit the parenthesis.
  3. If the function only has 1 line of code that it executes and immediatly returns a value, then " { } " and " return" can be omitted
  4. If the function has 2 or more parameters, parenthesis can't be omitted.

Good Luck

Shay

Just a guess, but if you're on the question about passing parameters note that when two or more parameters are being passed they should be enclosed in parentheses.

So for that question, the blank needs to have a set of parentheses containing both parameter names separated by a comma.

Complete the code below to create an arrow function with two parameters — string and letter — const remove = => { let regex = new RegExp(letter, 'g'); return string.replace(regex,''); }
