Can I execute a string command in Node?

Question

If I construct a function or list of commands that are stored in a string variable, is there a way I can execute them in node and retain what is returned in another variable? i.e.

var result = executeMyCoolStringCommands(myStringVariableWithCommands);

Answer 1

option -e will let you run arbitary text as node.js source code:

node -e "console.log(JSON.stringify({}))"

Answer 2

Sure, we all know evils of using eval, however the npm module eval avoids its use yet executes a string

var _eval = require('eval')
var res = _eval('var x = 123; exports.x = x')

console.log("here is res ", res);

which outputs :

here is res  { x: 123 }
