Similarly, we can also remove the last element of an array by using thesplice() methodwith-1as an argument. constfruits=["apple","banana","grapes"];fruits.splice(-1);console.log(fruits);// ["apple", "banana"] You can also read,how to remove first element of an array in JavaScript...
PHP Array Functions You can use the array_pop() function to remove an element or value from the end of an array. The array_pop() function returns the last value of array. If the array is empty (or the variable is not an array), then the returned value is NULL....
One of the most frequent operations we perform on an array is removing the last element. There are a few different ways to do this - but one of the most common is to use thepop()method. Consider you have the following array:
privateclassItrimplementsIterator<E>{ intcursor;// index of next element to return intlastRet = -1;// index of last element returned; -1 if no such intexpectedModCount = modCount; 这是Itr对象的几个类成员变量,其中我...
You can use the PHP array_pop() function to remove an element or value from the end of an array. The array_pop() function also returns the last value of array. However, if the array is empty (or the variable is not an array), the returned value will be NULL....
