re: The shortest way to conditional insert properties into an object literal VIEW POST

re: Interesting trick, but what if our value is 0 which can be a valid value to use? So our code: 𝐯𝐚𝐫 𝐜𝐨𝐢𝐧𝐬 = 𝟎; 𝐯𝐚𝐫 𝐨𝐛𝐣 = { 𝐧𝐚𝐦𝐞: "𝐉𝐨𝐡𝐧", ...𝐜𝐨𝐢...
 

So there is no point to use the trick in this way if 0 is a valid amount as well.

Remember that on the left you put the condition, so you may write like the following:

𝐯𝐚𝐫 𝐜𝐨𝐢𝐧𝐬 = 𝟎;
𝐯𝐚𝐫 𝐨𝐛𝐣 = {
  𝐧𝐚𝐦𝐞: "𝐉𝐨𝐡𝐧",
  ...𝐜𝐨𝐢𝐧𝐬>=0 && { 𝐜𝐨𝐢𝐧𝐬𝐀𝐦𝐨𝐮𝐧𝐭: 𝐜𝐨𝐢𝐧𝐬 }
}
