-## 1. Call Stack +## 1. काल स्टैक -

The call stack is a mechanism that the JavaScript interpreter uses to keep track of function execution within a program. In JavaScript, functions are executed in the order they are called. The call stack follows the Last In, First Out (LIFO) principle, meaning that the last function pushed onto the stack is the first one to be executed.

+

काल स्टैक एक ऐसा तन्त्र (mechanism) सै, जिसका इस्तेमाल जावास्क्रिप्ट दुभाषिया (interpreter) एक प्रोग्राम कै भीतर फंक्शन नै चलाण का हिसाब राखण खातर करै सै। जावास्क्रिप्ट में, फंक्शन उसी क्रम में चालै सैं जिस क्रम में उन्हें बुलाया जावै सै। काल स्टैक पिछला अन्दर, पहला बाहर (LIFO) सिद्धांत पर काम करै सै, मतलब यो सै कि जो आखिरी फंक्शन स्टैक में धकेला जावै सै, वोए सबसे पहला चालै सै।

-

According to the ECMAScript specification, the call stack is defined as part of the execution context. Whenever a function is called, a new execution context is created and placed at the top of the stack. Once the function completes, its execution context is removed from the stack, and control returns to the previous context. This helps manage synchronous code execution, as each function call must complete before the next one can begin.

+

ECMAScript नियम कै हिसाब तँ, काल स्टैक नै "चालू होण आळे सन्दर्भ" (execution context) का एक हिस्सा बताया गया सै। जब भी कोई फंक्शन बुलाया जावै सै, तो एक नया चालू होण आळा सन्दर्भ बण जावै सै और स्टैक कै ऊपरले हिस्से में धर दिया जावै सै। ज्यों ही फंक्शन पूरा हो जावै सै, तो उस का चालू होण आळा सन्दर्भ स्टैक तँ हटा दिया जावै सै, और नियंत्रण पहले आळे सन्दर्भ कै धौरै वापिस भाज्जै सै। या चीज़ एक साथ चालण आळे (synchronous) कोड नै संभालण में मदद करै सै, क्यूंकि हर फंक्शन नै पूरा होणा ज़रूरी सै ताकै अगला चाल सकै।

Primitive Types +## 2. साधारण प्रकार -

According to the ECMAScript specification, JavaScript has six primitive data types: string, number, bigint, boolean, undefined, and symbol. These types are immutable, meaning their values cannot be altered. There is also a special primitive type called null, which represents the intentional absence of any object value.

+

ECMAScript नियम कै हिसाब तँ, जावास्क्रिप्ट में छै (6) साधारण डेटा प्रकार सैं: स्ट्रिंग (string), नंबर (number), बिगइंट (bigint), बूलियन (boolean), अनडिफाइंड (undefined), अर सिंबल (symbol)। यो प्रकार "बदलण आळे कोन्या" (immutable) सैं, मतलब इनके मूल्य बदले कोनी जा सकैं। एक ख़ास साधारण प्रकार नल (null) भी सै, जो किसी भी ऑब्जेक्ट का जानबूझकर गैर-हाज़िर होणा बतावै सै।

-

Primitive values are directly assigned to a variable, and when you manipulate a primitive type, you're working directly on the value. Unlike objects, primitives do not have properties or methods, but JavaScript automatically wraps primitive values with object counterparts when necessary (e.g., when calling methods on strings).

+

साधारण मूल्य सीधे एक वैरिएबल नै दिए जावैं सैं, और जब तूँ एक साधारण प्रकार नै बदळो सै, तो तूँ सीधे मूल्य पर काम करै सै। ऑब्जेक्ट्स तँ अलग, साधारण प्रकार में गुण (properties) या तरीके (methods) कोनी होंदे, पर जब ज़रूरी होवै सै तो जावास्क्रिप्ट अपने आप साधारण मूल्यां नै ऑब्जेक्ट्स तँ लपेट देवै सै (जैड़ै, स्ट्रिंग पर कोई तरीका बुलाण लाग जावै)।

Value Types and Reference Types +## 3. मूल्य-आधारित अर संदर्भ-आधारित प्रकार -

According to the ECMAScript specification, value types are stored directly in the location that the variable accesses. These include types like number, string, boolean, undefined, bigint, symbol, and null. When you assign a value type to a variable, the value itself is stored.

+

ECMAScript नियम कै हिसाब तँ, मूल्य-आधारित प्रकार सीधे उस जगहां पर जमा (store) करे जावैं सैं, जिस्से वैरिएबल पहुँच (access) करै सै। इनमां नंबर, स्ट्रिंग, बूलियन, अनडिफाइंड, बिगइंट, सिंबल, अर नल जये प्रकार शामिल सैं। जब तूँ एक मूल्य-आधारित प्रकार नै एक वैरिएबल नै देवो सै, तो मूल्य ख़ुद जमा हो जावै सै।

-

Reference types, on the other hand, are objects stored in the heap. Variables assigned to reference types actually store references (pointers) to the objects, not the objects themselves. When you assign a reference type to another variable, both variables reference the same object in memory.

+

दूसरी तरफ, संदर्भ-आधारित प्रकार वो ऑब्जेक्ट सैं जो हीप (heap) में जमा हो सैं। वो वैरिएबल जिन्हें संदर्भ-आधारित प्रकार दिए जावैं सैं, वे असल में ऑब्जेक्ट्स कै संदर्भ (pointers) नै जमा करै सैं, न कि ख़ुद ऑब्जेक्ट नै। जब तूँ एक संदर्भ-आधारित प्रकार नै दूसरे वैरिएबल नै देवो सै, तो दोनों वैरिएबल मेमोरी में एकै ऑब्जेक्ट नै दर्शावैं सैं।

Implicit, Explicit, Nominal, Structuring and Duck Typing +## 4. अप्रकट, प्रकट, नामकरण, ढाँचा अर डक टाइपिंग -

The ECMAScript specification defines JavaScript as a dynamically typed language, meaning that types are associated with values rather than variables, and type checking occurs at runtime. There are various ways JavaScript manages types:

+

ECMAScript नियम कै हिसाब तँ, जावास्क्रिप्ट नै डायनैमिक रूप तँ टाइप करी गई ज़बान बताया गया सै, मतलब यो सै कि प्रकार (types) वैरिएबल की बजाय मूल्यां तँ जुड़े हों सैं, अर प्रकार की जाँच (type checking) कोड चालण कै टैम (runtime) पर होवै सै। जावास्क्रिप्ट प्रकार नै कई तरीकां तँ संभालै सै:

-

Implicit Typing (or Type Coercion): This occurs when JavaScript automatically converts one data type to another when required. For instance, JavaScript might convert a string to a number during an arithmetic operation. While this can simplify some code, it can also lead to unexpected results if not handled carefully.

+

अप्रकट टाइपिंग (Implicit Typing) (या प्रकार मजबूरी/Type Coercion): या तब होवै सै जब ज़रूरत पड़ण पर जावास्क्रिप्ट अपने आप एक डेटा प्रकार नै दूसरे में बदळ देवै सै। मिसाल खातर, गणित कै काम (arithmetic operation) कै दौरान जावास्क्रिप्ट एक स्ट्रिंग नै नंबर में बदळ सकै सै। यो तरीक़ा कुछ कोड नै आसान तो कर सकै सै, पर जै ध्यान तँ ना संभालया जावै तो अण-सोची दिक्कतें भी पैदा कर सकै सै।

-

Explicit Typing: Unlike implicit typing, explicit typing involves manually converting a value from one type to another using functions like Number(), String(), or Boolean().

+

प्रकट टाइपिंग (Explicit Typing): अप्रकट टाइपिंग तँ उलट, प्रकट टाइपिंग में फ़ंक्शन जैड़ै Number(), String(), या Boolean() का इस्तेमाल करकै तूँ ख़ुद मूल्य नै एक प्रकार तँ दूसरे में बदळो सै।

-

Nominal Typing: JavaScript doesn't natively support nominal typing, where types are explicitly declared and checked. However, TypeScript, a superset of JavaScript, brings this feature to help catch type errors during development.

+

नामकरण टाइपिंग (Nominal Typing): जावास्क्रिप्ट में नामकरण टाइपिंग पैदाइश तँ (natively) कोनी होवै, जिस्में प्रकार नै साफ़-साफ़ बताणा और जाँचणा पड़ै सै। हाँलांकि, टाइपस्क्रिप्ट (जावास्क्रिप्ट का एक बड़ा रूप) या सुविधा ल्यावै सै ताकै डेवलपमेंट कै दौरान प्रकार की ग़लतियाँ नै पकड़ी जा सकैं।

-

Structural Typing: In this type system, types are based on the structure or properties of the data. JavaScript is a structurally typed language where objects are compatible if they share the same structure (i.e., the same set of properties and methods).

+

ढाँचागत टाइपिंग (Structural Typing): इस प्रकार कै सिस्टम में, प्रकार डेटा कै ढाँचै (structure) या गुणां (properties) पर आधारित हों सैं। जावास्क्रिप्ट एक ढाँचागत रूप तँ टाइप करी गई ज़बान सै, जित ऑब्जेक्ट तभी ठीक मान्या जावै सै जब उनमां एक जैसा ढाँचा हो (म्हणै, एक जैसे गुण अर तरीके हों)।

-

Duck Typing: This is a concept where an object's suitability is determined by the presence of certain properties and methods, rather than by the actual type of the object. JavaScript relies heavily on duck typing, where behavior is inferred from an object's properties rather than its declared type.

+

डक टाइपिंग (Duck Typing): यो एक असूल सै जित एक ऑब्जेक्ट काम करन खातर ठीक सै या कोन्या, यो ऑब्जेक्ट कै असल प्रकार की बजाय उसमें मौजूद खास गुणां अर तरीकां तँ तय होवै सै। जावास्क्रिप्ट डक टाइपिंग पर घणा निर्भर करै सै, जित ऑब्जेक्ट का बर्ताव उसकी बताई गई टाइप की बजाय उसके गुणां तँ अनुमान लगाया जावै सै।
