Javascript: Is there an equivalent of lua's _G in JavaScript?

In lua, I can do the following:

_G.print("Hello world")
print("Hello world")

And it will both print the same string to the screen. Is there a way to access the global object in javascript? I mean like

_G.console.log === console.log
true

It will be really helpful in my use case (I want to prevent any code injection on my website by scanning the global object for changes)

global lua object javascript

In browsers you can use window or self. In Node you can use global. However this is not standardized in general, but there is a proposal for standardizing it. The proposal also shows an environment agnostic way to get the global object:

var getGlobal = function () {
    // the only reliable means to get the global object is
    // `Function('return this')()`
    // However, this causes CSP violations in Chrome apps.
    if (typeof self !== 'undefined') { return self; }
    if (typeof window !== 'undefined') { return window; }
    if (typeof global !== 'undefined') { return global; }
    throw new Error('unable to locate global object');
};
