To put it simply, string is a character (string)...
And array is an array... you can put numbers, characters, etc.!!!

Previous example:

Copy code The code is as follows:

var str = "liuzhanqi";
document.write(str["length"]);//Equivalent to str.l ength
var str = string.fromcharcode(72, 101, 108, 108, 111, 33);
document.write(str); //Each integer is encoded as unicode and concatenated into a string.
var str1 = "liu".localecompare("zhan");//Compare the current string and the parameter string according to the default comparison rules provided by this system
document.write(str1);//
var str2 = "liu".slice(1);//Extract a substring from the current string
document.writeln(str2);
document.writeln("se nki".split(' '));//Split the string with a delimiter and return an array.
document.write('liu'.fontcolor('red'));
document.write('liu'.fixed()); // Make the string appear as a fixed-width character
document.write('liu'.strike());//Add strikethrough to the string
document.write("senki".sub());//Displayed as subscript
document.write("senki".sup());//Displayed as superscript

charCodeAt(index) Returns the Unicode encoding of the character at the string index. The value is an integer between 0 and 65535. If the index exceeds the range, NaN is returned.

concat(str2) Concatenates the string str2 to the current string to form a new string.

anchor(anchar_name) creates an anchor point

link(url) Add hyperlink

charAt(index) Returns a character at the position specified by index in the string
