Can an array have multiple data types JavaScript?

The Array in JavaScript is a global object which contains a list of items.

It is similar to any variable, in that you can use it to hold any type of data.

An element inside an array can be of any type, and different elements of the same array can be of different types : string, boolean, even objects or other arrays..

How many kinds of elements an array can have?

If the array has 5 elements, we can use int(random(5)) to choose the element and we will get back the integer numbers 0, 1, 2, 3 and 4, never 5, which is exactly what we want. In an array that has 5 elements, the first element is 0 and the last one is 4.

What are the different data types can be used for arrays?

Is an array a data type?

In computer science, an array type is a data type that represents a collection of elements (values or variables), each selected by one or more indices (identifying keys) that can be computed at run time during program execution. Such a collection is usually called an array variable, array value, or simply array.

Can Arraylist hold different types?

ArrayLists cannot hold primitive data types such as int, double, char, and long (they can hold String since String is an object, and wrapper class objects (Double, Integer). Like an array, it contains components that can be accessed using an integer index.

What is the two dimensional array?

A 2D array has a type such as int[][] or String[][], with two pairs of square brackets. … The elements of a 2D array are arranged in rows and columns, and the new operator for 2D arrays specifies both the number of rows and the number of columns. For example, int[][] A; A = new int[3][4];

What are the kinds of array?

What are various types of arrays? Explain themOne dimensional (1-D) arrays or Linear arrays: In it each element is represented by a single subscript. The elements are stored in consecutive memory locations. … Multi dimensional arrays: (a) Two dimensional (2-D) arrays or Matrix arrays: In it each element is represented by two subscripts.

What is Array give example?

For example, “int numbers[ 5 ][ 6 ]” would refer to a single dimensional array of 5 elements, wherein each element is a single dimensional array of 6 integers. By extension, “int numbers[ 12 ][ 5 ][ 6 ]” would refer to an array of twelve elements, each of which is a two dimensional array, and so on.

Can tuples have different data types?

A tuple can have any number of items and they may be of different types (integer, float, list, string, etc.). A tuple can also be created without using parentheses. This is known as tuple packing. Creating a tuple with one element is a bit tricky.

Can a tuple contain a list?

That’s because tuples don’t contain lists, strings or numbers. They contain references to other objects. The inability to change the sequence of references a tuple contains doesn’t mean that you can’t mutate the objects associated with those references.

Can list have different data types?

There are no inherent problems in having multiple data types in a list. … By convention, tuples are used when the composition of the sequence is fixed; lists are used when you might add to or remove from the sequence.

What is the data type of array subscript?

Array Subscripts An array subscript is not part of the variable name. An array subscript allows Mathcad to display the value of a particular element in an array. It is used to refer to a single element in the array.

Can you store mixed data types in one array?

Yes we can store different/mixed types in a single array by using following two methods: Method 1: using Object array because all types in . … We can use Add() method of ArrayList class to add different data types to the ArrayList collection.

Which data types can a list hold Python?

Python has six standard Data Types: Numbers. String. List. Tuple.

Can you store a mixture of data types in an array?

Can you store a mixture of data types in an array? No, you cannot. All the items in an array must be of the same data type. … A number that identifies a specific element in an array.
