如何在 {} 括号中使用循环和条件？

Question

I am not able to use if and for loop inside {} why? Anything wrong?

sendTextMessageWithPromise(assignerID, `Value : ${if(x==0) console.log(x)}`)

Answer 1

These are called template literals . And you can't use if statements or for loops inside them. What you can do is a conditional check with ternary operator .

That's how you can do it:

console.log(`Answer: ${ (age == 18)? 'age is 18' : 'age is not 18' }`);
