Yes.

alert((5+"").charAt(0))

This part of js is not very intuitive, please test thoroughly:
<script>

x = 5 + ""
alert(x) // 5 string

x = x + x
alert(x) // 55 string

y = x + x * 7
alert(y) // 55385 string

y = x * 7 + x
alert(y) // 38555 string

y = y + 1
alert(y) // 385551 string

y = x * 7 + x * 1
alert(y) // 440 number!

y = y + 1
alert(y) // 441 number!
</script>
