shift() The shift() method removes the first element from an array and returns that removed element. This method changes the length of the array.
The array_shift() function removes the first element from an array, and returns the value of the removed element.
To remove the first n elements from an array:Call the splice method on the array, passing it the start index and the number of elements to remove as arguments. For example, arr. splice(0,2) removes the first two elements from the array and returns a new array containing the removed elements.
pop() function: This method is use to remove elements from the end of an array. shift() function: This method is use to remove elements from the start of an array. splice() function: This method is use to remove elements from the specific index of an array.
The easiest way is using shift(). If you have an array, the shift function shifts everything to the left.
var arr = [1, 2, 3, 4];
var theRemovedElement = arr.shift(); // theRemovedElement == 1
console.log(arr); // [2, 3, 4]
Just use arr.slice(startingIndex, endingIndex).
If you do not specify the endingIndex, it returns all the items starting from the index provided.
In your case arr=arr.slice(1).
const a = [1, 2, 3]; // -> [2, 3]
// Mutable solutions: update array 'a', 'c' will contain the removed item
const c = a.shift(); // prefered mutable way
const [c] = a.splice(0, 1);
// Immutable solutions: create new array 'b' and leave array 'a' untouched
const b = a.slice(1); // prefered immutable way
const b = a.filter((_, i) => i > 0);
const [c, ...b] = a; // c: the removed item
Plunker
$scope.remove = function(item) {
$scope.cards.splice(0, 1);
}
Made changes to .. now it will remove from the top
There is a function called shift().
It will remove the first element of your array.
There is some good documentation and examples.
