How do I fix this "assignment" in google-apps-script? - google-apps-script

Question

So I started editing this code so I can make it create words. Eventually making a replication of Alan Turing's Bombe. However after my last edit my "assignment" became invalid? Now I am confused, especially since I am not 100% familiar with google-apps-script.
Here is what my current script currently says:
function bombeCode2() {
var fastRotor = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N",
"O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"
];
var mediumRotor = fastRotor;
var slowRotor = fastRotor;
var rows = 26;
var columns = 26;
for (var i = 0; i < rows; i++) {
Logger.log('Outer Loop: value of i : ' + i);
// Logger.log("Partition for Outer Loop");
// Logger.log(" ");
var fastRotorValue = fastRotor[i];
for (var j = 0; j < columns; j++) {
Logger.log('-Inner Loop value of j : ' + j);
//var fastRotorValue = fastRotor[i];
var medRotorValue = mediumRotor[j];
// Logger.log("---- " + fastRotorValue + " " + medRotorValue);
for (var k = 0; k < 26; k++) {
// Logger.log('---- XXXX Third Loop value of k : ' + k);
//var fastRotorValue = fastRotor[i];
//var medRotorValue = mediumRotor[j];
var slowRotorValue = slowRotor[k];
if ("---- XXXX " + fastRotorValue + " " + medRotorValue + " " + slowRotorValue = "WEATHER") {
Logger.log("---- XXXX " + fastRotorValue + " " + medRotorValue + " " + slowRotorValue = "WEATHER")
}
// Logger.log("---- XXXX " + fastRotorValue + " " + medRotorValue + " " + slowRotorValue);
};
//var objectNumberValuePair = {"0":"A", "1":"B", "2":"C","3":"D","4":"E","5":"F","6":"G","7":"H","8":"I",
// "9":"J","10":"K","11":"L","12":"M","13":"N","14":"O","15":"P","16":"Q","17":"R",
// "18":"S","19":"T","20":"U","21":"V","22":"W","23":"X","24":"Y","25":"Z"}
// Logger.log(slowRotorValue = objectNumberValuePair);
// Logger.log(medRoterValue = objectNumberValuePair);
// Logger.log(fastRoterValue = objectNumberValuePair);
}
}
}
Yes I know that half of it is useless as is. However this is only so I can remember what everything is/does.
Does anyone know how to fix this "assignment?" Here is the error message it gives me "Invalid assignment left-hand side. (line 1, file "B. Test 2")."

Answer 1

You are doing a variable assignment in an if-statement.
Try using valid js-syntax:
var compareValue = "---- XXXX " + fastRotorValue + " " + medRotorValue + " " + slowRotorValue;
if (compareValue === "WEATHER"){
Logger.log(compareValue + ' === "WEATHER"');
}
