Creating global variables using node modules in different files

Question

I want to create global variables in main.js using data.js. This would allow me to add as many entries in colors, creating variables in main.js without copy-pasting. This doesn't work and I have no idea what to do, I'm pretty sure this is a good example, I might have spelled something wrong but you get the idea.

//data.js

module.exports = {
   colors: {
      red: ['10','40','25'],
      black: ['50','99','1'],
      yellow: ['67','87','53'] 
   }
}

//main.js
 
data = require(./data.js);
colors = Object.keys(data);

for(i = 0; i < colors.length; i ++){
    eval(colors[i]) = data.colors[colors[i]];
}

console.log(black);
//wanted output: ['50','99','1']

Answer 1

Putting the eval part all together fixes it.

//main.js
 
data = require(./data.js);
colors = Object.keys(data);

for(i = 0; i < colors.length; i ++){
    eval(colors[i] + '= data.colors[colors[i]]');
}

console.log(black);
//output: ['50','99','1']
