xml2json - "X2JS is not defined"

I'm using xml2json for the first time to get an review feed to populate on a website and I keep getting errors such as;
Uncaught ReferenceError: X2JS is not defined
and
Uncaught TypeError: Cannot set property 'X2JS' of undefined
I can't seem to find a solution, this is the code;

Apologies if I've gone about this in the wrong way. I've done;
npm install xml2json
Which didn't flag up any errors but I still can't seem to get the data to load correctly.

Solution that after you import <script> from package x2js, you should use window.X2JS to get constructor of X2JS. Almost packages implementing for both NPM and browser, the browser version usually use via object window, because it is shared and free connected in almost browsers.
This is my demo for the solution: https://jsfiddle.net/huynhsamha/2evdgt7r/
In my demo, I've include package x2js from NPM here https://unpkg.com/x2js#3.2.3/x2js.js
var X2JS = window.X2JS;
var x2js = new X2JS();
const data = {
a: {
b: 1
},
c: [1, 2]
}
console.log(x2js.js2xml(data))
// <a><b>1</b></a><c>1</c><c>2</c>

Screeps: Get the id of an object

I tried to write a code that prevents 2 creeps (harvester) from going to the same destination and binds them to that destination until its full.
on line 55 I get an error which is understandable
55: creep.memory.targetID = targets[checkTarget].id;
for a reason that I am not seeing targets[checkTarget] is null
Can anyone tell me what i am doing wrong?
var roleHarvester = {
/** #param {Creep} creep **/
run: function(creep) {
if (!creep.memory.targetID) creep.memory.targetID = "not given";
console.log(creep.memory.targetID);
if (creep.carry.energy < creep.carryCapacity) {
var nearestSource = creep.pos.findClosestByPath(FIND_SOURCES_ACTIVE);
if (creep.harvest(nearestSource) == ERR_NOT_IN_RANGE) {
creep.moveTo(nearestSource, {
visualizePathStyle: {
stroke: '#ffaa00'
}
});
}
} else {
if (creep.memory.targetID != "not given") {
console.log("should not be not given");
if (Game.getObjectById(creep.memory.targetID).hits == Game.getObjectById(creep.memory.targetID).hitsMax) {
creep.memory.targetID = "not given";
var targets = creep.room.find(FIND_STRUCTURES, {
filter: (structure) => {
return (structure.structureType == STRUCTURE_SPAWN ||
structure.structureType == STRUCTURE_EXTENSION ||
structure.structureType == STRUCTURE_TOWER) && structure.energy < structure.energyCapacity;
}
});
} else {
if (creep.transfer(Game.getObjectById(creep.memory.targetID), RESOURCE_ENERGY) == ERR_NOT_IN_RANGE) {
creep.moveTo(Game.getObjectById(creep.memory.targetID), {
visualizePathStyle: {
stroke: '#ffffff'
}
});
}
}
} else {
var targets = creep.room.find(FIND_STRUCTURES, {
filter: (structure) => {
return (structure.structureType == STRUCTURE_SPAWN ||
structure.structureType == STRUCTURE_EXTENSION ||
structure.structureType == STRUCTURE_TOWER) && structure.energy < structure.energyCapacity;
}
});
console.log(targets);
for (var checkTarget in targets) {
console.log(checkTarget);
console.log(targets[checkTarget]);
for (var name in Game.creeps) {
if (targets[checkTarget] = Game.getObjectById(Game.creeps[name].memory.targetID)) {
var fail = true;
break;
}
var fail = false;
}
if (fail == true) continue;
console.log(Game.getObjectById(targets[checkTarget]));
creep.memory.targetID = targets[checkTarget].id;
break;
}
}
}
}
};
module.exports = roleHarvester;

Something wrong in the following if condition:
for(var name in Game.creeps) {
if(targets[checkTarget] = Game.getObjectById(Game.creeps[name].memory.targetID)){
Probably you mean == ?

How to count number of if/for/while/switch/try statements using esprima

I want to display files that have more then 3 if/for/while/switch/try statements (same as sonar) so far I have code that traverse the tree and count statements for whole file:
var fs = require('fs');
var esprima = require('esprima');
function traverse(obj, fn) {
for (var key in obj) {
if (obj[key] !== null && fn(obj[key]) === false) {
return false;
}
if (typeof obj[key] == 'object' && obj[key] !== null) {
if (traverse(obj[key], fn) === false) {
return false;
}
}
}
}
fs.readFile(process.argv[2], function(err, file) {
var syntax = esprima.parse(file.toString());
var count = 0;
traverse(syntax, function(obj) {
if (obj.type == "TryStatement" || obj.type == "ForStatement" ||
obj.type == "IfStatement" || obj.type == "WhileStatement"
obj.type == "SwitchStatement") {
count++;
}
});
console.log(process.argv[2] + ' ' + count);
});
How can I count path in the program for instance for this code:
try {
if (foo == 10) {
for (var i=0; i<foo; ++i) {
if (i % 5 == 0) {
var j = i;
while(j--) {
console.log(j);
}
}
}
}
} catch(e) {
if (e instanceof Error) {
if (e.stack) {
console.log(e.stack);
}
}
}
it should show 5 and 2 not 7.

How can I create empty JSON keys (nested or not) using a string?

I currently have this code built in JS, but it's really, really ugly.
Is there any better way to approach it?
The way it works basically is pushing a string like app.chat.test to be the key, and value like teststr.
I test the lengths to see if the "parent" key is there, otherwise we build it.

OF course it's possible, a simple loop will perfeclty do the job.

I just assigning to a temporary variable each sublevel. When i'm on the last i'm assigning the value.

Yes you can, using the javascript reduce function on the array created from the splitted string.
function namespaceCreateExceptLast(representationOfElementToCreate, baseNamespace) {
var tokens;
if (typeof representationOfElementToCreate !== 'string')
throw new Error('Expecting string as first parameter');
if (baseNamespace === undefined)
baseNamespace = window;
tokens = representationOfElementToCreate.split('.');
// Remove the last element (which will contain the value)
tokens.pop();
// Use reduce to create part by part your new object
return tokens.reduce(function (prev, property) {
if (typeof prev !== 'object') {
throw Error('One property is already defined but not an object, namespace creation has failed', property);
return undefined;
} else {
if (!prev[property])
prev[property] = {};
return prev[property];
}
}, baseNamespace);
};
Then you can have:
function constructJson(jsonKey, jsonValue){
let jsonObj = langFile;
var lastItem = namespaceCreateExceptLast(jsonKey, jsonObj);
var lastKey = jsonKey.substring(jsonKey.lastIndexOf('.') + 1);
lastItem[lastKey] = jsonValue;
}
I have added some comments and exceptions to help you understand how it's done, but it's mainly based on the reduce function which you can easily get help for (https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Objets_globaux/Array/reduce).

How to check if object.subobject.subsubobject exists or not in javascript?

The hierarchy can be very deep, So how to check if the a property exists somewhere within the root object ? If not then create it.
I have the following html
<div id="container">
<div id="level-1">
<input id="value-1" group="a.b" name="c" value="some-value-1">
</div>
</div>
Now i would like to put the value of this input into a javascript object based on the parent attribute.
Desired output is
{
"a" : {
"b" : {
"c" : "some-value-1"
}
}
}
My Effort :
function traverse(id, obj) {
var methodName = "traverse";
var elementToTraverse = document.getElementById(id);
var currentElementLength = elementToTraverse.childNodes.length;
if (currentElementLength > 0) {
var children = getChildNodes(elementToTraverse);
for (var ch in children) {
var currentChild = children[ch];
//ignore the text nodes
if (currentChild.nodeType == 3) {
continue;
}
if (currentChild.nodeType == 1 && currentChild.childNodes.length > 0 && currentChild.id != "") {
//call without the object argument as it has already been constructed.
traverse(currentChild.id, obj);
}
else if (currentChild.nodeType == 1 && currentChild.id != "" && currentChild.getAttribute('name') != null) {
if (DEBUG) {
logOnConsole(methodName, currentChild.getAttribute('name') + "--" + currentChild.id, logLevel.INFO);
}
var group = currentChild.getAttribute('group') || null;
var name = currentChild.getAttribute('name');
var value = getValue(currentChild);
if (value == "" || value == undefined) {
if(group){
if(isNull(obj[group])){
obj[group] = new Object();
}
obj[group][name] = "";
}
else{
obj[name] = "";
}
}
else if(group){
if(isNull(obj[group])){
obj[group] = new Object();
}
obj[group][name] = value;
}
else {
obj[name] = value;
}
}
else {
if (DEBUG) {
logOnConsole(methodName, "Element not useful. \n" + currentChild.nodeName, logLevel.INFO);
}
}
}
}
return obj;
}
I call it via traverse('container-id', new Object()) but this will work for a single value in the group rather than a nested structure.

Try this
function isExist(obj, path) {
patharray = path.split(".");
for(var i=0;i < patharray.length; i++) {
obj = obj[patharray[i]];
if(obj === undefined) return false
}
return true;
}
document.body.innerHTML = isExist({subobject:{subsubobject:{test: 34}}}, 'subobject.subsubobject');
