Changes to Summary description of `clientLeft/clientTop`. I **think** this is what was meant.

added a missing word

The solution explanation is not very obvious so added another example to make things clear

quick description:
before: .catch(f) is the same as promise.then(null, f)
after: .catch(f) is the same as .then(null, f)

Changed the reference to each item of the array since it was previously defined as the variable word.

When assigning the static method `staticMethod` to the `User` class, as a property directly, no parentheses should be used after `User`, since this leads to an error: `SyntaxError: Unexpected token '('`. For this reason, such parentheses have to be removed.

in the control control forms section, fixed mistake selectionEnd and selectionStart were both said to be start position

Removed duplicated `also`.
