Primitive number values have a Number object equivalent that wraps around the value and provides access to constants and methods that can be used to work with number values.
A new number can be…
A typical program will add data to list, like products in a shopping cart, which can be stored in an array. The shopping cart array can have items added, removed, and rearranged.
To accomplish tasks like this, arrays come with many built-in methods that provide a lot of flexibility when working with them.
This article will examine how to create arrays, access data with them, and work with arrays.
Functions include the following characteristics:
There are several different ways to control the flow of the program, including conditional statements and loops. Each offer the ability for the programmer to evaluate different aspects of the program before continuing down a particular path or repeating a piece of code a specified number of times.
if...else statement. Using the ternary operator can help to condense code, although it is sometimes criticized for contributing to less transparent and readable code compared to the
The ternary operator, as the name implies, requires three operands. The ternary operator statement includes a condition, which is evaluated…
In contrast to unary operators, which require just one operand to perform its operation, binary operators require two operands — as the name applies. Mozilla Web Docs (MDN) has an extensive section on expressions and operators, which include binary operators. …
Being able to perform operations such as arithmetic, combining, comparing, performing logical checks, and other operations on values transform them into dynamic values. Different types have available different operations. And some operations behave differently depending on the types involved. Operators can be broken down into a few groups.
A unary operation is an operation that…
The foundation of any programming language is data. Without data, creating a program is very difficult, if not impossible.
JavasScript allows programmers to work with a lot of…
