Hello, readers . In today's blog I am trying to give multiple ways to concatenate a string using JavaScript.
Basically the term “Concatenate” means joining two or more strings and returns a new joined string .
As there are various operators used in JavaScript for performing various Airthmetic calculations such as assigning and comparing the values.
For concatenating a string , we can use following methods such as :-
- The Addition operator ( + )
- The Assignment operator ( += )
- The built-in concat () method
Example for each method is given below :-
-
Concatenating a string using addition method :-
html>
<body>
<script type="text/JavaScript">
var str1 = "Welcome";
var str2 = "To";
var str3 = "JavaScript";
var result = str1 +" "+ str2 +" "+ str3;
document.write(result);
</script>
</body>
</html>
In this code , I have created a string with a variable name as str1 ,str2 , str3 and assign values to it.
Now for the result, I have created a variable with a result name and had added all three strings in it.
Now on calling the result variable , we will get the desired result.
2. Concatenating a string using Assignment operator ( += ):-
<html>
<body>
<script type = "text/javascript">
var str1 = "Welcome";
str1 += " To";
document.write(str1);
</script>
</body>
</html>
In this code , I have created a variable with name as srt1 and assigned a value to it.
Now to the string , I have used addition assignment operator that adds the value of the right operand to a variable and hence, assigned the result to the created variable.
Now on calling the srt1 variable, we will get the desired result.
3. Concatenating a string using Concatenate Method
<html>
<body>
<script type="text/JavaScript">
var str1 = "".concat("Welcome ","To ","Javascript");
document.write(str1);
</script>
</body>
</html>
Now , in this code for Concatenating a string , we will use concat() method for adding the strings.
Now on calling the created srt1 variable , we will get the desired result.
Conclusion:-
Hence , I have explained the multiple ways of Concatenating a string using JavaScript with the help of various operators.
