A closure is used when an inner function has access to the variables and arguments of its outer function. The inner function accesses three range chains: Its variables; the variables and arguments of the outer function; global variables. Hoisting in JavaScript is a mechanism that helps to place function declarations and variables at the beginning of their scope before JS code execution. Hoisting moves functions and variables to the beginning of their scope regardless of where they are declared, whether their scope is global or local.
JavaScript works with prototype-based inheritance. This means that each object has its property associated with another object, its prototype. The prototype object has its prototype until it reaches null as a prototype. A promise is an object that represents the completion or failure of an asynchronous operation and its value. This can be either a resolved value or a reason why it could not be resolved. A promise can have three states: fulfilled, pending, and rejected. Promise users can include callbacks to manage the fulfilled value or the reason for failure.
JavaScript framework knowledge is a strong plus
An experienced JavaScript coder has the most programming experience and can choose the right JS framework and other tools for your project. JavaScript coders also need to know the Node.js framework for server-side rendering, API development, and real-time network app development. Your ideal dedicated programmers should also be able to use the JS framework used in your app project. Keep in mind that the knowledge of React.js, one of the most popular JS frameworks, is a great advantage for every JavaScript developer.
