Actually the function is simply returning an object and we are assigning it into a variable and then we use that variable to access all the key value pairs of that object simple -.-
what if prices are different for different model ?? do write like this add MRP argument/parameter : function mobile(model_no,MRP){ return { model:model_no, price:MRP }; };
Factory Function in JavaScript function mobile(){ return { model: "Galaxy", price: function(){ return "Price is Rs.3400"; } }; } var samsung= mobile(); document.write("Price is "+samsung.price()); document.write(" Price is "+samsung.model);
Bro how come atfer using factory function ,document.write(samsung.model) = 'Galaxy' of mobile when i type document.write(mobile.model) it doesn't give me anthing
@@milanpoudel3737 as much i understood about this logic is : you can create multiple object instances and just access your properties. now when ur using constructor object u were creating properties name / key for every object . the problem was key/properties ko code was repeating .so just in factory function u create object instances and u acess properties using it .(no need to write key for every object)
Yes, Ammad is correct. You need to start your left curly braces "{" from same return line. Like " return { " Bottom is the solution: function mobile(model_no) { return { model: model_no, price: function() { return "Price is Rs. 300"; } }; } var lg = mobile("lg 101"); console.log(lg.model + ' and ' + lg.price());
Sir, you have explained all the single topics in detail but you have never explained why we use the anonymous function. may you give me an answer, please?
Sir i wrote bellow code but model parameter showing "undefined " i am not getting how to correct it, Please help me. Thanks in advance function config(model, ram, rom) { return { detail: model, ram,rom, price: function() { return " 15000 TK"; } }; } var samsung = config("GalaxyJ7", "2GB", "16GB"); document.write(samsung.model + " " + samsung.ram + " " + samsung.rom + "" );
//Factory Function with multiple parameters.... function mobile(model_no,type,size,cost){ return { //it is returning the below object model: model_no, make: type, ram: size, price: cost }; } var samsung = mobile('galaxy','S3','4GB',20000); var nokia = mobile('nokia','3310','1GB',10000); var apple = mobile('iphone','10','4GB',70000); console.log(samsung); console.log(nokia); console.log(apple);
I didn't understand a single second of this video. Needed more examples. Also what I see in all youtube tutorials there is no example related to web development. All tutorials are only explaining codes

hello dear i hav an error .. Uncaught SyntaxError: Unexpected token ' : ' in " price : "
function mobile(model_no)
{
return
{
model: model_no,
price : function()

return "Price is Rs. 300";

please tell me how to solve
return ka body tag same line se start hoga
function mobile(model_no)
{
return{
model: model_no,
price: function(){return "Price is Rs. 300";}
}
}
Yes, Ammad is correct.
You need to start your left curly braces "{" from same return line. Like " return { "
Bottom is the solution:
function mobile(model_no) {
return {
model: model_no,
price: function() {
return "Price is Rs. 300";
}
};
}
var lg = mobile("lg 101");
console.log(lg.model + ' and ' + lg.price());
quit programming. start pani puri thela

Which browser you are using?
you have to write samsung.detail instead of .model.
