ts-node:tldr:94ffa
The command ts-node --eval '${console.log("Hello World")}' is used to execute TypeScript code directly from the command line using the ts-node package.
Here's a breakdown of the command:
-
ts-node: It is a package that allows you to run TypeScript code directly without compiling it to JavaScript. It provides a TypeScript REPL (Read-Eval-Print Loop) and also supports executing TypeScript files directly. -
--eval: It is an option that specifies that the following argument should be treated as code to evaluate and execute. -
${console.log("Hello World")}: This is the code to execute. In this case, it logs the string "Hello World" to the console using theconsole.log()function.
Note that the code is wrapped inside ${}. This is because the command is encapsulated within single quotes ('), and enclosing the code within ${} allows the code to be evaluated and interpolated.
So, when you run the command ts-node --eval '${console.log("Hello World")}', it will execute the TypeScript code console.log("Hello World") and output Hello World to the console.
