String functions String functions can be used to create and manipulate strings. Note that the string functions are case sensitive, e.g. you must use $string.getCharAt and not $string.getcharat. In this section • $string.length • $string.getCharAt • $string.setCharAt • $string.equalsIgnoreCase • $string.startsWith • $string.endsWith • $string.indexOf • $string.lastIndexOf • $string.substring • $string.toLowerCase • $string.toUpperCase • $string.trimLeft • $string.trimRight • $string.trim • $string.split • $string.replace
