How to get String output as in single quote in javascript

Advance thanks, Question looks like simple but i could not able to find the solution.
function sumStrings(a, b)
{
return +a + +b;
}
sumStrings('1','2') //=>3
Expected output
sumStrings('1','2') // => '3'

After addition, add ' to beginning and end.
function sumStrings(a, b){
return "'" + (Number(a) + Number(b)) + "'";
}
console.log(sumStrings('1','2'));

function sumStrings(a, b) {
// Separate decimal part here
var pointa = a.indexOf(".");
var pointb = b.indexOf(".");
var deca = pointa != -1 ? a.substring(pointa + 1) : "0";
var decb = pointb != -1 ? b.substring(pointb + 1) : "0";
if (deca.length < decb.length)
deca += (Math.pow(10, decb.length - deca.length)).toString().substring(1);
else
decb += (Math.pow(10, deca.length - decb.length)).toString().substring(1);
var inta = pointa != -1 ? a.substring(0, pointa) : a;
var intb = pointb != -1 ? b.substring(0, pointb) : b;
// console.log(deca + " " + decb);
var decc = addBigInt(deca, decb);
var intc = addBigInt(inta, intb);
if (decc.length > deca.length) {
intc = addBigInt(intc, "1");
decc = decc.substring(1);
}
var lastZero = decc.length - 1;
while (lastZero >= 0 && decc[lastZero] == "0") {
lastZero--;
}
if (lastZero >= 0)
return intc + "." + decc.substring(0, lastZero + 1);
else
return intc;
}
function addBigInt(a, b) {
var inda = a.length - 1;
var indb = b.length - 1;
var c = [];
const zero = "0".charCodeAt(0);
var carry = 0;
var sum = 0;
while (inda >= 0 && indb >= 0) {
var d1 = a.charCodeAt(inda--) - zero;
var d2 = b.charCodeAt(indb--) - zero;
sum = (d1 + d2 + carry);
carry = Math.floor(sum / 10);
sum %= 10;
c.unshift(sum);
}
if (inda >= 0) {
while (carry && inda >= 0) {
sum = a.charCodeAt(inda--) - zero + carry;
c.unshift(sum % 10);
carry = Math.floor(sum / 10);
}
c.unshift(a.substring(0, inda + !carry));
} else {
while (carry && indb >= 0) {
sum = b.charCodeAt(indb--) - zero + carry;
c.unshift(sum % 10);
carry = Math.floor(sum / 10);
}
c.unshift(b.substring(0, indb + !carry));
}
if (carry)
c.unshift(carry);
return c.join("");
}
console.log(sumStrings("1","2"));
console.log(sumStrings("800","9567"));
console.log(sumStrings("99.1","1"));
console.log(sumStrings("00103","08567"));
console.log(sumStrings("50095301248058391139327916261.5","81055900096023504197206408605"));

If you want to escape the single quote, you can try to add a backslash before the single quote.
i.e.
var x = '\'5\'';

With the new template literal you can try this:
a=`'5'`;
console.log(a);

error in loader: JSON Parse error: Invalid number located in jquery

I am having trouble getting a page to load because the js loader is being effected by an error in query JSON parse.
This is the error in noted by Safari.
error in loader: JSON Parse error: Invalid number at line 2618: http://localhost:8888/iicode/jquery-1.11.2.min.js
here is a snippet of the code at line 2618, which has the asterix.
var vc = m.now(), wc = /\?/, xc = /(,)|(\[|{)|(}|])|"(?:[^"\\\r\n]|\\["\\\/bfnrt]|\\u[\da-fA-F]{4})*"\s*:?|true|false|null|-?(?!0\d)\d+(?:\.\d+|)(?:[eE][+-]?\d+|)/g;
m.parseJSON = function(b) {
if (a.JSON && a.JSON.parse)
**return a.JSON.parse(b + "");**
var c, d = null, e = m.trim(b + "");
return e&&!m.trim(e.replace(xc, function(a, b, e, f) {
return c && b && (d = 0), 0 === d ? a : (c = e || b, d+=!f-!e, "")
})) ? Function("return " + e)() : m.error("Invalid JSON: " + b)
}, m.parseXML = function(b) {
var c, d;
if (!b || "string" != typeof b)
return null;
try {
a.DOMParser ? (d = new DOMParser, c = d.parseFromString(b, "text/xml")) : (c = new ActiveXObject("Microsoft.XMLDOM"), c.async = "false", c.loadXML(b))
} catch (e) {
c = void 0
}
return c && c.documentElement&&!c.getElementsByTagName("parsererror").length || m.error("Invalid XML: " + b), c
};
Here is the the first few lines of the js loader that the error is disabling, and I have no idea why. Safari highlighted the part that I asterix.
(function(window, jQuery) {
var namespace = 'de.kubikfoto', engine = null, args = {}, jsonFiles = {}, xmlFiles = {}, filesToLoad = 1, oldloadXML = null, oldloadJSON = null;
function logerror(errortext) {
if (typeof console === "object" && typeof console.error === "function") {
**console.error("error in loader: " + errortext)**
}
}
Any help would be appreciated my website is currently at a standstill.
As some have noted a potential problem with the Ajax, here is the call.
the ajax call I found was this : v[d](k[d]);
if (i = Mc(Ic, k, b, v)) {
v.readyState = 1, h && n.trigger("ajaxSend", [v, k]), k.async && k.timeout > 0 && (g = setTimeout(function() {
v.abort("timeout")
}, k.timeout));
try {
t = 1, i.send(r, x)
} catch (w) {
if (!(2 > t))
throw w;
x( - 1, w)
}
} else
x( - 1, "No Transport");
function x(a, b, c, d) {
var j, r, s, u, w, x = b;
2 !== t && (t = 2, g && clearTimeout(g), i = void 0, f = d || "", v.readyState = a > 0 ? 4 : 0, j = a >= 200 && 300 > a || 304 === a, c && (u = Oc(k, v, c)), u = Pc(k, u, v, j), j ? (k.ifModified && (w = v.getResponseHeader("Last-Modified"), w && (m.lastModified[e] = w), w = v.getResponseHeader("etag"), w && (m.etag[e] = w)), 204 === a || "HEAD" === k.type ? x = "nocontent" : 304 === a ? x = "notmodified" : (x = u.state, r = u.data, s = u.error, j=!s)) : (s = x, (a ||!x) && (x = "error", 0 > a && (a = 0))), v.status = a, v.statusText = (b || x) + "", j ? o.resolveWith(l, [r, x, v]) : o.rejectWith(l, [v, x, s]), v.statusCode(q), q = void 0, h && n.trigger(j ?

trailing zeros with comma functionality using php

Hi I've code in javascript which is working fine but same functionality I want in php language I find different sources on the internet but didn't get successes.
Javascript Code:
Number.prototype.formatMoney = function(c, d, t){
var n = this,
c = isNaN(c = Math.abs(c)) ? 2 : c,
d = d ? "." : d,
t = t ? "," : t,
s = n < 0 ? "-" : "",
i = parseInt(n = Math.abs(+n || 0).toFixed(c)) + "",
j = (j = i.length) > 3 ? j % 3 : 0;
return s + (j ? i.substr(0, j) + t : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + Math.abs(n - i).toFixed(c).slice(2) : "");
};
function trailingZerosWithComma() {
var costAmount = $("#costAmount").val();
if(costAmount != "") {
var costAmountReplace = parseFloat(costAmount.replace(/\,/g,''));
$("#costAmount").val((costAmountReplace).formatMoney(2, '.', ','));
}
}
<input type="text" name="costAmount" id="costAmount" onblur="trailingZerosWithComma();">
But I need this in php
Number.prototype.formatMoney = function(c, d, t){
var n = this,
c = isNaN(c = Math.abs(c)) ? 2 : c,
d = d ? "." : d,
t = t ? "," : t,
s = n < 0 ? "-" : "",
i = parseInt(n = Math.abs(+n || 0).toFixed(c)) + "",
j = (j = i.length) > 3 ? j % 3 : 0;
return s + (j ? i.substr(0, j) + t : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + Math.abs(n - i).toFixed(c).slice(2) : "");
};
var costAmountReplace = parseFloat(costAmount.replace(/\,/g,''));

There is a javascript file called custom.js
Here is the code to find you will see the date you have to modify,

SO: what does this js mean? I am studying SO source code [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

It is a closure.
It is a part of your code that can have own variables that will not be shared with the rest of your code.
And the final parenthesis have the parameters passed to this closure.
Like this:
(function (what, howmany){
for (var i = howmany; i--;){
alert(what);
}
})("John",3);
In your example the closure is being calling with jquery object as parameter.
With this you can isolate the execution of this part of your code. It is powerful and must be well know to programming real javascript.
