How to get the last character of the string:
"linto.yahoo.com."
The last character of this string is "."
How can I find this?

An elegant and short alternative, is the
String.prototype.slice method.
Just by:
str.slice[-1];
A negative start index slices the string from length+index, to length, being index -1, the last character is extracted:
"abc".slice[-1]; // "c";

Use charAt:
The charAt[] method returns the character at the specified index in a string.
You can use this method in conjunction with the
length property of a string to get the last character in that string.
For example:
const myString = "linto.yahoo.com.";
const stringLength = myString.length; // this will be 16
console.log['lastChar: ', myString.charAt[stringLength - 1]]; // this will be the string

You can achieve this using different ways but with different performance,
1. Using bracket notation:
var str = "Test";
var lastLetter = str[str.length - 1];
But it's not recommended to use brackets. Check the reasons here
2. charAt[index]:
var lastLetter = str.charAt[str.length - 1]
This is readable and fastest among others. It is most recommended way.
3. substring:
str.substring[str.length - 1];
4. slice:
str.slice[-1];
It's slightly faster than substring.
You can check the performance here
With ES6:
You can use str.endsWith["t"];
But it is not supported in IE. Check more details about endsWith here

str.charAt[str.length - 1]
Some browsers allow [as a non-standard extension] you to shorten this to:
str[str.length - 1];

Use substr with parameter -1:
"linto.yahoo.com.".substr[-1];
equals "."
Note:
To extract characters from the end of the string, use a negative start number [This does not work in IE 8 and earlier].

An easy way of doing it is using this :]
var word = "waffle"
word.endsWith["e"]

Using the String.prototype.at[] method is a new way to achieve it
const s = "linto.yahoo.com.";
const last = s.at[-1];
console.log[last];Read more about at here

Try this...
const str = "linto.yahoo.com."
console.log[str.charAt[str.length-1]];

You can get the last char like this :
var lastChar=yourString.charAt[yourString.length-1];

Use the JavaScript charAt function to get a character at a given 0-indexed position. Use length to find out how long the String is. You want the last character so that's length - 1. Example:
var word = "linto.yahoo.com.";
var last = word.charAt[word.length - 1];
alert['The last character is:' + last];

If you have or are already using lodash, use last instead:
_.last[str];
Not only is it more concise and obvious than the vanilla JS, it also safer since it avoids Uncaught TypeError: Cannot read property X of undefined when the input is null or undefined so you don't need to check this beforehand:
// Will throws Uncaught TypeError if str is null or undefined
str.slice[-1]; //
str.charAt[str.length -1];
// Returns undefined when str is null or undefined
_.last[str];

You can use the following. In this case of last character it's an overkill but for a substring, its useful:
var word = "linto.yahoo.com.";
var last = ".com.";
if [word.substr[-[last.length]] == last]
alert["its a match"];

You can use this simple ES6 method
const lastChar = [str] => str.split[''].reverse[].join[','].replace[',', ''][str.length === str.length + 1 ? 1 : 0];
// example
console.log[lastChar["linto.yahoo.com."]];This will work in every browsers.
