// CLASS TOPICS : Primitive vs reference DATA TYPES
// PRIMITIVE TYPE
// x = 10;
// y = x;
// x = 20;
// console.log(x,y);
// here x and y both are same but locating different positions in memory and saved at diff places
// REFERENCE TYPE
// x = {name:"shagun",email:"abc@gmail.com"};
// y = x;
// x = {name:"abc"};
// console.log(x,y);
// both are pointing same location on memory but later on x is pointing a diff location
// REFERENCE TYPE
// x = {name:"shagun",email:"abc@gmail.com"};
// y = x;
// x.name = "testing name";
// console.log(x,y);
// both are pointing same location on memory. so if one is change other will also reflect the same change
// PRIMITIVE TYPES
// numbers , string , boolean , null , undefined
// REFERENCE TYPES
// object , array , functions are reference type
// CLASS TOPICS : STRING DATA TYPE // "H" , "E" , "L", "O" // string is a combination of few characters // we can re-assign variables as done below // myValue = 'hello' // console.log(myValue, 'called') // myValue = 1 // console.log(myValue, 'called 2') // myValue = [1,2,3] // console.log(myValue,'called 3') // we can access charac from string same as we can do with array's // myValue = "hello" // myCharac = myValue[2] // console.log(myCharac); // we can create space b/w charac too // myValue = "hello " + "world" // console.log(myValue) // behind the scenes space is also being stored like this: ["h","e","l","l","o",""] // we can use \n to print data in next line // myValue = "hello my name is: \n shagun" // console.log(myValue); // we can also use \t to create space between words in the same line
