while the reverse is obtained with String#to...
innerText vs innerHTML vs label vs text vs textContent vs outerText
...t will.
innerHTML returns the HTML as its name indicates. Quite often, in order to retrieve or write text within an element, people use innerHTML. textContent should be used instead. Because the text is not parsed as HTML, it's likely to have better performance. Moreover, this avoids an XSS attack ...

TSQL - Cast string to integer or return default value
...ng main differences:
My logic does not tolerate occurrences of . or , in order to mimic the behaviour of native INT conversions. '1,234' and '1234.0' return NULL.
Since it does not use local variables, my function can be defined as an inline table-valued function, allowing for better query optimiz...
