JavaScriptda Scope Chain
JavaScriptda Scope Chain tushunchasi bu - JavaScript engine ni o'zgaruvchilar va fungsiyalarni scopelar ichidan qidirib topish mexanizmidir.
Scope Chain o'zgaruvchi e'lon qilingan scopedan boshlab global scope ga qarab qidirib boradi. Buni yaxshiroq tushunish uchun quyidagi misolni ko'rib o'tamiz.
const y = 20;
function function1() {
const x = 100;
const function2 = function () {
console.log(x); // x o'zgaruvchisi dastavval function2 ni scopidan qidiriladi topolmagach o'zidan bitta yuqoridagi scopega chiqadi va x ni o'qib oladi x = 100
};
var function3 = function () {
console.log(y); // y o'zgaruvchisi dastavval function3 ni scopidan qidiriladi topolmagach o'zidan bitta yuqoridagi function1 ni scopega chiqadi, u yerdan ham topolmagach global scopega chiqadi va y ni tanib oladi y = 20
};
function2();
function3();
}
function1();
