TypeScript - String charAt()
charAt() is a method that returns the character from the specified index. Characters in a string are indexed from left to right. The index of the first character is 0, and the index of the last character in a string, called stringName, is stringName.length 1.
Syntax
string.charAt(index);
Argument Details
index − An integer between 0 and 1 less than the length of the string.
Return Value
var str = new String("This is string"); console.log("str.charAt(0) is:" + str.charAt(0)); console.log("str.charAt(1) is:" + str.charAt(1)); console.log("str.charAt(2) is:" + str.charAt(2)); console.log("str.charAt(3) is:" + str.charAt(3)); console.log("str.charAt(4) is:" + str.charAt(4)); console.log("str.charAt(5) is:" + str.charAt(5));
On compiling, it will generate the same code in JavaScript.
Its output is as follows −
str.charAt(0) is:T str.charAt(1) is:h str.charAt(2) is:i str.charAt(3) is:s str.charAt(4) is: str.charAt(5) is:i
