is there an AngularJS way of checking if a value exists in an array
var array1 = ["a","b","c"]
i'm trying to do this..
var array2 = ["c", "d", "e"]
angular.forEach(array2, function (a) {
if (a /*is NOT in array1*/) {
array1.push(a);
} else {
return false
}
});
You can use Array.indexOf which will return -1 if it's not found or the index of the value in the array.
So in your case:
if (array2.indexOf(a) < 0) {
array1.push(a);
}
You just need to use native Array.prototype.indexOf to check if value is in array or not:
var array2 = ["c", "d", "e"]
angular.forEach(array2, function (a) {
if (array2.indexOf(a) === -1) {
// a is NOT in array1
array1.push(a);
}
});

var fruits = ["Banana", "Orange", "Apple", "Mango"];
var n = fruits.includes("Mango");
