Hi makenzi.exc,

Refer below example.

HTML

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title></title>
    <style type="text/css">
        body { font-family: Arial; font-size: 10pt; }
    </style>
</head>
<body>
    <script type="text/javascript">
        // Using == operator
        console.log('Using == operator');
        var isValid = "false";
        console.log(isValid == 'true');

        isValid = "True";
        console.log(isValid.toLowerCase() == 'true');

        // Using === operator
        console.log('Using === operator');
        var isSuccess = "true";
        console.log(isSuccess === 'true');

        isSuccess = "True";
        console.log(isSuccess.toLowerCase() === 'true');

        // Using Boolean function
        console.log('Using Boolean function');
        var isExists = "true";
        console.log(Boolean(isExists));

        // Using JSON.parse method
        console.log('Using JSON.parse method');
        var boolValue = "true";
        console.log(JSON.parse(boolValue));
    </script>
</body>
