I'm trying to create a new variable using the Proxy type from the ES6 specification:
myProxy: Proxy;
However, I'm encountering the following error:
Cannot find name 'Proxy'.
Can anyone point me in the right direction to resolve this issue?

If you have set your target to es2015 or are including the library for es2015 using the lib option, then you can utilize a Proxy. It's important to note that a Proxy is not a type, but rather a constructor according to the es2015 lib:
interface ProxyConstructor {
revocable<T extends object>(target: T, handler: ProxyHandler<T>): { proxy: T; revoke: () => void; };
new <T extends object>(target: T, handler: ProxyHandler<T>): T;
}
declare var Proxy: ProxyConstructor;
To create a proxy, you must call the constructor like so:
let foo = new Proxy({ value: 0 }, {
get: (v) => v.value * 2
});
The variable type of foo will be the same as the type of the target object.
