Setting attributeTwo using an if statement. What is the correct way to do this?
var testBoolean = true;
var object = {
attributeOne: "attributeOne",
attributeTwo: if (testBoolean) { "attributeTwo" } else { "attributeTwoToo" },
}

1@Rooster—that would be the conditional operator, also called a ternary operator. :-)RobG– RobG2014-02-04 20:51:05 +00:00Commented Feb 4, 2014 at 20:51

@RobG short hand if is a much better and easier to remember name ;-PRooster– Rooster2014-02-04 21:20:51 +00:00Commented Feb 4, 2014 at 21:20

1No problemwith that, but in a technical forum it's good to include the appropriate technical term. :-)RobG– RobG2014-02-04 23:12:53 +00:00Commented Feb 4, 2014 at 23:12

No, however you can use the ternary operator:
var testBoolean = true;
var object = {
attributeOne: "attributeOne",
attributeTwo: testBoolean ? "attributeTwo" : "attributeTwoToo"
}

You can use an if statement, if it is within a immediately invoked function.
var x = {
y: (function(){
if (true) return 'somevalue';
}())
};

You can't use an if statement directly, but you can use ternary operator (aka conditional operator) which behaves the way you want. Here is how it would look:
var testBoolean = true;
var object = {
attributeOne: "attributeOne",
attributeTwo: testBoolean ? "attributeTwo" : "attributeTwoToo"
}
Comments
you can also do by this method
var testBoolean = true;
var object = {
attributeOne: "attributeOne"
}
1
if(testBoolean){
object.attributeTwo = "attributeTwo"
}else{
object.attributeTwo = "attributeTwoToo"
}
2
object.attributeTwo = testBoolean ? "attributeTwo" : "attributeTwoToo"

you can put a conditional statement like this way, where conditional statement also works for object's key also.
let inbox = true;
let assign = {...(inbox ? {assign_to: 2} : {})};
console.log("assign", assign);
inbox = false;
assign = {...(inbox ? {assign_to: 2} : {})};
console.log("assign", assign);

I know this question is really old but i haven't seen anyone give this answer so i'll just drop this here, you can actually pass a function inside the property of your object like this:
var testBoolean = true;
const genericFunc = (testBoolean) => {
if(testBoolean !== true){
return 'False'
}else {
return 'True'
}
}
var object = {
attributeOne: "attributeOne",
attributeTwo: genericFunc(testBoolean),
}
console.log('Object',object)As long as the function you pass actually has a return statement, it'll work!

To add a value conditionally in an object you can do something like this
const condition = true;
var obj = {
key: condition ? value1 : value2
}
