I have a piece of code below that says "Unexpected assignment expression." where (foo = bar).

function bar() {}

var foo;

foo || (foo = bar);

I have tried to create a variable before it and assign it to the variable. But it gives another error where foo is saying "Expected an assignment or function call and instead saw an expression." where foo || foobar (foobar is the variable i had to create when i tried var foobar = bar) (basically foo || foobar). I keep running into a wall trying to figure this one out. How would you recode this lint free?

Thanks.

You can't defined variables using string names like in PHP.

Would this be the same?

if (foo === undefined) {
bar;
} else {
foo;
}

I don't believe that would work either.
I think you are looking for something like this if you are not a fan of ternaries: I don't see a need for an else statement to say that foo = foo. Of course it equals foo if it's not "undefined"

ok cool, thank you. I was basically trying to NOT use ternaries like you said. wanted to get it back to a normal if statement for readability. Then I was going to optimize later.

I have always loved ternaries and find them very quickly readable compared to an IF statement, but to each their own
