Use replace method with a regular expression to replace all special characters in JavaScript.
stringToReplace.replace(/[^\w\s]/gi, '')The caret (^) character is the negation of the set [...], gi say global and case-insensitive (the latter is a bit redundant but I wanted to mention it) and the safelist in this example is digits, word characters, underscores (\w) and whitespace (\s).

Example Replace all special characters in JavaScript
A simple example code uses a regular expression to replace them with the empty string.
<!doctype html>
<head>
<script>
var s = "img_realt@ime_tr~ading3$";
var res = s.replace(/[^\w\s]/gi, '')
console.log(res)
</script>
</head>
<body>
</body>
</html>
Output:

const str = "abc's test#s";
console.log(str.replace(/[^a-zA-Z ]/g, ""));Output: abcs tests
