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 stringYou 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
3str.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:
2To 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")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);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
var firstName = "Ada";
var lastLetterOfFirstName = firstName[firstName.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");var string = "Hello";
var fg = string.length;
fg = fg - 1;
alert(string[fg]);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.
