Can I write an if statement within a Javascript object when setting an attribute?

Question

Setting attributeTwo using an if statement. What is the correct way to do this?

var testBoolean = true;

var object = {
  attributeOne: \"attributeOne\",
  a         


        

Answer 1

Indeed you can but why don't you do the conditional statement before assigning it to object attribute. The code would be nicer.

Answer 2

No, however you can use the ternary operator:

var testBoolean = true;

var object = {
  attributeOne: "attributeOne",
  attributeTwo: testBoolean ? "attributeTwo" : "attributeTwoToo"
}

Answer 3

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"

Answer 4

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"
}

Answer 5

You can use an if statement, if it is within a immediately invoked function.

var x = {
  y: (function(){
       if (true) return 'somevalue';
     }())
};
