Very simple if/else statements seem to be working backwards - if-statement

Question

I have been looking at this simple if/else statement in another larger project and I can't seem to find what I am doing wrong.
I have inserted Logger.log() in both if statements to try to root out the problem.
When I run the code, I get the following Log:
[19-02-24 08:50:05:427 PST] var Campus = Baylor
[19-02-24 08:50:05:428 PST] var TSTCCampus = TSTC
[19-02-24 08:50:05:428 PST] if IS= statement executed
[19-02-24 08:50:05:428 PST] else NOT= executed
The two variables are clearly NOT equal but the if = executes and the else != executes.
What am I doing wrong?
function myFunction() {
// call the Current Reults sheet and identify the Last Row of Responses
var RawFormResponsesSheet = SpreadsheetApp.getActive().getSheetByName("Current Results");
var CurrentSubmission = RawFormResponsesSheet.getLastRow(); // Retruns the Value of the Last Submission Row Number
var Campus = RawFormResponsesSheet.getRange(CurrentSubmission,3).getValue();
// call the Email Data sheet and identify certain cell values
var EmailDataSheet = SpreadsheetApp.getActive().getSheetByName("Email Data")
var TSTCCampus = EmailDataSheet.getRange(3, 4).getValue();
var BaylorCampus = EmailDataSheet.getRange(4, 4).getValue();
Logger.log("var Campus = " + Campus)
Logger.log("var TSTCCampus = " + TSTCCampus)
if (Campus = TSTCCampus){Logger.log ("if IS= statement executed")}
else {Logger.log ("else IS= executed")}
if (Campus != TSTCCampus){Logger.log ("if NOT= statement executed")}
else {Logger.log ("else NOT= executed")}
}

You need to use == as comparison operator.
There are 3 = operators/commands:
= is used to set the value of a variable
== equality operator, returns true if the elements have same value, performs type conversion
=== identity operator, similar to ==, but no type conversion
The following explains what type conversion is.
"5" == "5" returns true
"5" == 5 returns true
"5" === "5" returns true
"5" === 5 returns false
somevar = 5 assigns and returns 5, which is a truthy value, and thus if (x = 5) { will always execute the conditional body. Similarly if (x = 0) { will never execute the conditional body, because it assigns and returns 0, which is falsy.
