Conversion object by namespace

Question

I need to convert \"flat object\" like this (input data):

{
   \'prop1\': \'value.1\',
   \'prop2-subprop1\': \'value.2.1\',
   \'prop2-subprop2\': \'value.2         


        

Answer 1

var input = {
    "property1": "value1",
    "property2.property3": "value2",
    "property2.property7": "value4",
    "property4.property5.property6.property8": "value3"
}

function addProp(obj, path, pathValue) {
    var pathArray = path.split('.');
    pathArray.reduce(function (acc, value, index) {
        if (index === pathArray.length - 1) {
            acc[value] = pathValue;
            return acc;
        } else if (acc[value]) {
            if (typeof acc[value] === "object" && index !== pathArray.length - 1) {
                return acc[value];
            } else {
                var child = {};
                acc[value] = child;
                return child;
            }
        } else {
            var child = {};
            acc[value] = child;
            return child;
        }
    }, obj);
}

var keys = Object.keys(input);
var output = {};
keys.forEach(function (k) {
    addProp(output, k, input[k]);
});
console.log(output);
