<title>JavaScript Implement inverting strings</title>
</head>
<body>
<script language="javascript">
var str = "abcdefg";
(("").reverse().join(""));
</script>
</body>
</html>
The following is an explanation of the JS method used in the example:
1、join(): Returns the string value, which contains all elements of the array connected together, separated by the specified delimiter.
Format:(separator)
arrayObj Required option, Array object;
separator Required option. is a String object that serves as a separator between array elements in the final String object. If this parameter is omitted, the array elements are separated by a comma.
Note:()Equivalent to()
2、split(): Split a string into a substring, and return the result as a string array.
Format:([separator[, limit]])
stringObj Required option, String object or text to be decomposed.
separator Optional. A string or regular expression object that identifies whether one or more characters are used when separating a string. If this option is ignored, a single element array containing the entire string is returned.
limit Optional. This value is used to limit the number of elements in the return array.
3、reverse(): Returns an Array object whose element order is reversed.
Format:()
arrayObj Required option, Array object.
