Keywords in TypeScript

Keywords in programming languages such as TypeScript or JavaScript are reserved words that have some specific meaning, any keyword can not be used as an identifier because an identifier must follow rules in the naming of functions, variables, etc.

There are many keywords in the TypeScript such as let, const, var, and loop keywords such as for, while, do, etc. Another keyword that is recently being discussed in TypeScript is the “using” keyword which is gaining popularity, so it becomes important to understand how the using keyword can be used if it is implemented by the TypeScript organization successfully.

The new version of TypeScript introduces support for the “using” keyword used for the Explicit Resource Management feature in the ECMAScript, the using keyword is a keyword that aims to sort the facility for “cleanup” after creating any object.

The need for “using” keywords in both TypeScript and JavaScript is because it allows the developers to perform necessary actions like closing the connections for the network, release of memory, deletion of temporary files, etc.
