multiple things in If statement js

Question

Is there a way to set multiple things in an If statement? For example in the below code, I want to set both status and icon variables if something is true or false. This code is not working and I'm suspecting it's because && doesn't compute, but couldn't find a solution. Any suggestions?

var status;
var icon;
if(x.life > 0) {
    status = "Yes" && icon == "fa-check-circle-o"
} else {
    status = "No" && icon == " fa-times-circle-o"
}

Do you want to check the values or set the values ?

Sure, it is possible, However, it's not working currently because you're not correctly assigning the values. use a single ( = ) for assignment and double ( == ) for comparison (will return boolean).

Try this:

var status;
var icon;
if(x.life > 0) {
    status = "Yes";
    icon = "fa-check-circle-o";
} else {
    status = "No";
    icon = " fa-times-circle-o";
}

Make two separate statement instead of using && and use = instead of == when assigning value to variable.

var status;
var icon;
if(x.life > 0) {
   status = "Yes"; 
   icon = "fa-check-circle-o"
} else {
   status = "No";
   icon = " fa-times-circle-o";
}

There is no need to use && here which will make your statement a condition. And == will check for equality not compare items

var status;
var icon;
if(x.life > 0) {
    status = "Yes";
    icon = "fa-check-circle-o";
} else {
    status = "No";
    icon = " fa-times-circle-o";
}

You have to separate them with semicolon or enter.

   var status;
   var icon;
   if(x.life > 0) {
       status = "Yes";
       icon == "fa-check-circle-o";
   } else {
       status = "No";  
       icon == " fa-times-circle-o";
   }

Note that && is commonly used for boolean arguments;
example:

   if(x.life > 0 && y.life > 0) {
       status = "Yes";
       icon == "fa-check-circle-o";
   }

"Note that && is only used for boolean arguments" - No it's not. You can use it with any types.

If you want to set status based on the value of icon (since you have == in the original code):

var status;
var icon;
if (x.life > 0) {
    if (icon == "fa-check-circle-o") {
        status = "Yes";
    }
} else {
    if (icon == "fa-times-circle-o") {
        status = "No";
    }
}
