What is JavaScript with example?

JavaScript is a dynamic programming language that’s used for web development, in web applications, for game development, and lots more . It allows you to implement dynamic features on web pages that cannot be done with only HTML and CSS.

State is data over time Take for example a user logging into our application with their name and email. Before the user does so, we’re going to have a different state than after they have logged in (no user data then). After logging in, our state will have some new values, depending on what our application needs.15 Oca 2020

The state object is where you store property values that belongs to the component . When the state object changes, the component re-renders.

A state variable is one of the set of variables that are used to describe the mathematical “state” of a dynamical system . Intuitively, the state of a system describes enough about the system to determine its future behaviour in the absence of any external forces affecting the system.

No state is not a reserved word . I don’t think there are any specific to react but there are reserved keywords in javascript language.

There are only two possible and equally simple strategies here — either derive the polar or the cartesian coordinates . Both functions are based on the same unique state so it should never be possible for tests to pass individually but fail when cross referenced.
