The command ts-node --transpile-only ${filename-ts} is used to transpile and execute TypeScript files without performing type checking.

Here is an explanation of each part of the command:

• ts-node: ts-node is a TypeScript execution environment and REPL (Read-Eval-Print Loop) for Node.js. It allows you to directly run TypeScript files in a Node.js environment without the need for transpiling them separately.

• --transpile-only: This option tells ts-node to only transpile the TypeScript code and skip type checking. This can be useful when you want to quickly execute the code without waiting for the type checking process, especially in cases where you are confident that the code is correct.

• ${filename-ts}: This is a placeholder that represents the name of the TypeScript file you want to transpile and execute. You need to replace ${filename-ts} with the actual name of your TypeScript file, including the .ts file extension.

So, when you run the command ts-node --transpile-only ${filename-ts}, ts-node will transpile the specified TypeScript file to JavaScript and execute it, without performing type checking.
