There are two scopes: $scope.job and $scope.jobs.
I also have a variable called job;
If $scope.job is undefined, I want $scope.jobs to be assigned to the job variable using the following code: var job = $scope.jobs. However, if $scope.job is defined, then I want to assign it to that variable too.
if ( $scope.job ) {
var job = $scope.job;
} else {
var job = $scope.jobs;
}
But in shorthand notation:
I was originally going to leave a brief comment, but I now realize that it's much more beneficial to provide an explanation.
let position = $scope.position || $scope.positions;
undefined == false; // evaluates to trueThat's the gist of how it functions.
If $scope.position == undefined == false || $scope.positions == {...} == true.
If position is undefined, it will be considered false so the or operator will yield a true value.
It seems like your point is:
if ($scope.job)
var job = $scope.job;
else
{
var job = $scope.jobs;
$scope.job = $scope.jobs;
}
In that case, a more concise version would be:
var job = $scope.job = $scope.job || $scope.jobs;
If you prefer, you can opt for the ternary operator:
let position = $scope.position ? $scope.position : $scope.positions
or
let position = $scope.position === undefined ? $scope.position : $scope.positions
