The document contains code defining mock implementations of various browser APIs and properties like document, navigator, location, history and others. It includes empty implementations of methods like createElement, setAttribute, getElementsByTagName and properties like userAgent, hash to enable simulating a browser environment without an actual browser.

1. setAttribute: function() {},
getElementsByTagName: function() {
return []
}
}
},
location: {
hash: ""
}
} : document
, J = "undefined" == typeof window ? {
document: f,
navigator: {
userAgent: ""
},
location: {},
history: {},

2. }
} : document
, J = "undefined" == typeof window ? {
document: f,
navigator: {
userAgent: ""
},
location: {},
history: {},
CustomEvent: function() {
return this
},
addEventListener: function() {},
removeEventListener
