How to Remove Special Characters from a String in JavaScript ?

To remove special characters from a string in JavaScript, you can use the `replace` method with a regular expression pattern.

In this example,

We create a string variable str1 with a value of "Hello! World!".
We use the replace method with a regular expression pattern /[^a-zA-Z0-9 ]/g to replace all non-alphanumeric characters and spaces with an empty string.
Finally, we log the modified string str1 to the console.

let str1 = "Hello! World!";
str1 = str1.replace(/[^a-zA-Z0-9 ]/g, '');
console.log('Modified string:', str1);

Modified string: Hello World

In this example,

We create a string variable str2 with a value of "apple@banana".
We use the replace method with a regular expression pattern /[^a-zA-Z0-9 ]/g to replace all non-alphanumeric characters and spaces with an empty string.
Finally, we log the modified string str2 to the console.

let str2 = "apple@banana";
str2 = str2.replace(/[^a-zA-Z0-9 ]/g, '');
console.log('Modified string:', str2);

Modified string: applebanana
