You will want to number the entries a user adds. To get all of the number inputs, you can use the <dfn>querySelectorAll()</dfn> method.
The querySelectorAll() method returns a NodeList of all the elements that match the selector. A NodeList is an array-like object, so you can access the elements using bracket notation.
Declare an entryNumber variable and give it the value of targetInputContainer.querySelectorAll(). You do not need to pass an argument to the query selector yet.
You should have an entryNumber variable.
assert.match(addEntry.toString(), /entryNumber\s*=/);
Your entryNumber variable should have the value of targetInputContainer.querySelectorAll().
assert.match(addEntry.toString(), /entryNumber\s*=\s*targetInputContainer\.querySelectorAll\(/);
You should not pass an argument to querySelectorAll().
assert.match(addEntry.toString(), /entryNumber\s*=\s*targetInputContainer\.querySelectorAll\(\s*\)/);
