- Using String literal
- Using String object
Now we will check each way to create and we will try to understand it with the help of examples.
Using String literal:
In this method, we directly write var keyword and then literal for string and then we write a string in double quotes(” “). Follow this example to get a clear idea about this method.
<script> var str="Welcome To Owlbuddy"; document.write(str); </script>
Using String object:
In this method, we create String object using new keyword and then we pass a string in Object. Check the following example.
<script> var str=new String("Welcome to Owlbuddy."); document.write(str); </script>
