I want to know if there is a way to do this without make a full copy of the array and then splice the copy.
var arr = [{id:1, name:'name'},{id:2, name:'name'},{id:3, name:'name'}];
I need to temp remove element by his index and use the array without this element, but i dont want to change the original array.
You can give me way even with lodash.

To sort an array, without mutating the original array:Call the slice() method on the array to get a copy. Call the sort() method on the copied array. The sort method will sort the copied array, without mutating the original.
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.
You can remove elements from the end of an array using pop, from the beginning using shift, or from the middle using splice. The JavaScript Array filter method to create a new array with desired items, a more advanced way to remove unwanted elements.
Array.prototype.filter will create and return a new array consisting of elements that match the predicate.
function removeByIndex(array, index) {
return array.filter(function (el, i) {
return index !== i;
});
}
Even shorter with ECMAScript 6:
var removeByIndex = (array, index) => array.filter((_, i) => i !== index);
