Data properties

  • Math.E: number ES1

    Euler’s number, base of the natural logarithms, approximately 2.7182818284590452354.

  • Math.LN10: number ES1




None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

An annoted configuration file has been included below. However, there is no guarentee that this will work as-is on every machine.
