2022-10-04 20:23:19 A value in JavaScript is always of a certain type. For example, a string or a number.

There are 8 data types in JavaScript:


1. Number
2. String
3. BigInt
4. Boolean(logical type)
5. Null value
6. Undefined value
7. Objects

I will explain these types more deeper with examples

2022-10-04 16:59:10 There is strict mode in JavaScript which makes your code without any bugs and errors

Eliminates some JavaScript silent errors by changing them to throw errors.
Fixes mistakes that make it difficult for JavaScript engines to perform optimizations: strict mode code can sometimes be made to run faster than identical code that's not strict mode.
Prohibits some syntax likely to be defined in future versions of ECMAScript.

Use Strict


To invoke strict mode for an entire script, put the exact statement "use strict"; (or 'use strict';) before any other statements.


For example:

let name="Mirzoyoqub"


1) Strict mode in function: put the exact statement "use strict"; (or 'use strict';) in the function's body before any other statements.


function myStrictFunction() {
// Function-level strict mode syntax
'use strict';
function nested() {
return 'Hello World';
}
return Hi! I'm a strict mode function! ${nested()};
}


2) Strict mode in Classes - all Classes in JavaScript is in Strict mode Ochish/sharhlash

2022-10-04 08:12:02 Now Deep Copy Example:


The following snippet replaces the Object.assign() method by the JSON methods to carry a deep copy the person object:


let personalInfo = {
firstName: 'Mirzoyoqub',
lastName: 'Rashidov',
address: {
street: 'Chilonzor',
city: 'Tashkent',
}
};


let copiedpersonalInfo = JSON.parse(JSON.stringify(personalInfo));

copiedpersonalInfo.firstName = 'John'; // disconnected

copiedpersonalInfo.address.street = 'Oqqo'rg'on';

console.log(personalInfo);

2022-10-04 08:09:44 In this Example we can clear see about what is



Shallow Copy//////


let personalInfo = {
firstName: 'Mirzoyoqub',
lastName: 'Rashidov',
address: {
street: 'Chilonzor',
city: 'Tashkent',
}
};


let copiedPersonalInfo = Object.assign({}, personalInfo);

copiedPersonalInfo.firstName = 'John'; // disconnected

copiedPersonalInfo.address.street = 'Yunusobod'; // connected


console.log(copiedPersonalInfo); Ochish/sharhlash

2022-10-04 08:02:35 In JavaScript, you use variables to store values that can be primitive or references. When you make a copy of a value stored in a variable, you create a new variable with the same value. Ochish/sharhlash

2022-10-04 08:01:45 So now which is SHallow Copy and Deep Copy. And when we use it ? Ochish/sharhlash
