E0146: missing ':' in conditional expression
The ? :
ternary operator has three parts: the condition, the expression if
true, and the expression if false. It is a syntax error to omit the expression
if false:
for (let i = 1; i <= 100; ++i) {
console.log(i % 15 ? i);
}
document.querySelector("form input")?focus();
To fix this error, write :
followed by an expression:
for (let i = 1; i <= 100; ++i) {
console.log(i % 15 ? i : "FizzBuzz");
}
Alternatively, write ?.
instead of ?
to access an object's property:
document.querySelector("form input")?.focus();
