7/8/2023 0 Comments Types of javascript![]() ![]() Javascript 2020 (also known as ECMAScript or ES11) defines nine different data types. Then, we explain why data types matter and how the Javascript typeof operator keeps developers from making data typing mistakes. This article examines the different Javascript data types, including those added in the most recent versions of Javascript. The list of possible data types the typeof operator can identify has expanded over time, setting the stage for more complex data type interactions in the process. Javascript data types can be either simple or complex, ranging from a simple integer to a complex object, and encompass a wider range than data types in JSON. Since variables can change their type, the Javascript standard provides developers with a special operator called typeof that returns what type of value a variable holds. Javascript is a dynamic language, which means that any variable can hold any type of value.
