Execute Javascript using Node in terminal-CodePudding

Node.js allows to write JavaScript code that runs directly in a computer process itself instead of in a browser

Reading this, I try to open my terminal and run:

console.log('hello')

but I get zsh: unknown file attribute. The same happens with node console.log('hello').

If I instead create a file hello.js and put the console inside it and then I run:

node src/hello.js

it works. Why? What am I missing?

Sorry for the (maybe) stupid question

CodePudding user response：

It's because the console.log('hello') is being evaluated by your shell (zsh) before running the command and it has no idea what console.log('hello') is. You could use the -e or --eval arguments.

$ node -e "console.log('hello')"

If your using linux, first type node It will profile for you a REPL. which is essecially the excution terminal.

You can also do the same on windows
