A fairly basic JavaScript question, on a ternary condition how can I do to take action only on an if without the need of the else?
Example
(test) ? test1() : test2();
If you do not want anything to happen at Else, how would you look?
I tried, do as in PHP more did not work:
(!test) ?: test1();
This is possible with the && operator as follows:
(test) && test1();
In this other response, What it means the & & in between strings? ", I show how exactly the && function works in JavaScript, and why it's possible to use it this way ... it's actually a direct equivalence: a && b = > a ? b : a .
When you use this in the form of a statement, the resulting value is discarded, which makes it look like if without else .
