SwiftBlade errors

public enum SwiftBladeError: Error {
    case unknownJsError(String)
    case apiError(String)
    case initError(String)
}

In this case, SwiftBladeError has three possible cases, every conform to the Error protocol, indicating that they represent errors that can be thrown during the execution of a program.

The first case, unknownJsError, takes a String parameter and is used to represent an error that occurred while executing JavaScript code. The associated String value provides additional information about the error.

The second case, apiError, also takes a String parameter and is used to represent an error that occurred while interacting with an API. Again, the associated String value provides additional information about the error.

The third case, initError, takes a String parameter and is used to represent an error that occurred during the initialization of a SwiftBlade object. The associated String value provides additional information about the error.

By defining these cases as part of an enumeration, code that interacts with the SwiftBladeError type can use Swift's pattern matching syntax to handle errors in a structured way.

public struct BladeJSError: Error, Codable {
    public var name: String
    public var reason: String
}

In this case, BladeJSError has two properties, both of which are of type String. The name property represents the name of the JavaScript error that occurred, while the reason property provides additional information about the error.

The struct also conforms to two protocols: Error and Codable. By conforming to Error, this struct indicates that it represents an error that can be thrown during the execution of a program. By conforming to Codable, it indicates that it can be encoded and decoded to and from JSON format.

extension BladeJSError: LocalizedError {
public var errorDescription: String? {
        return NSLocalizedString("\(self.name): \(self.reason)", comment: self.reason);
    }
}

The implementation of errorDescription constructs a localized String using the NSLocalizedString function. The localized String consists of the name and reason properties of the BladeJSError instance, separated by a colon and a space.

The comment parameter of the NSLocalizedString function is set to the reason property of the BladeJSError instance. This parameter provides additional context about the error message for localization purposes.

By conforming to LocalizedError and implementing errorDescription, this extension allows Swift programs to provide localized descriptions of errors that occur while interacting with JavaScript code via the BladeJSError struct.
