VistasJavascript stops when first if condition fails, need to move it to second condition
I have the following code in which I ask it to check if either one of 2 dataLayer values is "!= false" then run the rest of the code.
However, code breaks as soon as the first condition fails and does not move to check the second condition. So, how can I let both conditions be checked as one of them will always be available in dataLayer?
function init() {
if (dataLayer.condition[1] != false || dataLayer.condition[2] != false) {
Do something
}
}
Below is the screenshot of the error I get when the first condition values are missing on the page.

You can use optional chaining (?.) for this, if your execution context is expected to support it:
if (dataLayer?.condition[1] != false || dataLayer?.condition[2] != false) {
// Do something
}
