Create a dynamic array for use in grunt concat - json

Question

I need to concatenate a set files based on variables I have defined my package.json.
// package.json
...
"layouts": [
{
"page": "home",
"version": "a"
},
{
"page": "about",
"version": "a"
},
{
"page": "contact",
"version": "b"
}
]
...
In grunt I am then building these into a JSON array and pumping it into the src parameter in my grunt-concat-contrib task.
// gruntfile.js
...
var package = grunt.file.readJSON('package.json'),
targets = package.layouts,
paths = [];
for (var target = 0; target < targets.length; target++) {
paths.push("layouts/" + targets[target]['page'] + "/" + targets[target]['version'] + "/*.php");
};
var paths = JSON.stringify(paths);
grunt.log.write(paths); // Writing this to console for debugging
grunt.initConfig({
concat: {
build: {
src: paths,
dest: 'mysite/Code.php',
options: {
separator: '?>\n\n'
}
}
}
});
...
My issue is that the paths variable is not working inside of the initConfig when it is assigned to JSON.stringify(paths).
If I manually input the array like the following that I copied from where I logged the paths variable to the console, it works!
var paths = ["layouts/home/a/*.php","layouts/about/a/*.php","layouts/contact/b/*.php"];
What am I missing?

Derp. I fixed it, I didn't need to JSON.stringify() the array.
Final working gruntfile is below:
// gruntfile.js
...
var package = grunt.file.readJSON('package.json'),
targets = package.layouts,
paths = [];
for (var target = 0; target < targets.length; target++) {
paths.push("layouts/" + targets[target]['page'] + "/" + targets[target]['version'] + "/*.php");
};
grunt.initConfig({
concat: {
build: {
src: paths,
dest: 'mysite/Code.php',
options: {
separator: '?>\n\n'
}
}
}
});
