In the editTask function
When we set the variables to get element, here is the part of codes
---
var editInput = listItem.querySelector("input[type=text");
---
Why here we miss a '' ] " in the ("input[type=text"); ?

My recommendation is to forget you ever saw this.

17,473 PointsYes, he should write the closing "]". I think the code works because the part in between "..." is a string. And the method search into the existent code, the string you pass inside the method. So, the string "input[type=text" is found in the code, as well as "input[type=te" will be found and even "input[type=t". If the error was something like "input[type=tex]" then this will cause an error, because this string doesn't exist in the document. The code not causing error, in this particular case, doesn't mean it's well written.

-```html
code inside
plus``` to close
del - and plus
But i fixed it.
