Check out this way, some how worked with single quotes...
let myvehicle = "car";
let weather = "rainy";
if(weather == 'rainy') {
if(myvehicle == 'car')
{
console.log("I go to the office");
}
else if(myvehicle == 'bike')
{
console.log("I Work from home");
}
}
else if(weather !== 'rainy')
{
console.log("I go to the office");
}
