Gado da Interfaces a cikin TypeScript: Amfani da Fa'idodi

Gado da mu'amala sune mahimman ra'ayoyi guda biyu a cikin TypeScript, kuma suna taka muhimmiyar rawa wajen haɓaka aikace-aikace. Anan akwai tattaunawa akan waɗannan ra'ayoyin da amfaninsu da fa'idodinsu wajen haɓaka aikace-aikacen:

 

Gado

Gado a cikin TypeScript yana ba wa ƙaramin aji damar gadon kadarori da hanyoyin daga babban aji. Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙaƙwalwa na iya haɓaka da haɓaka abubuwan da ke akwai na superclass.

Don amfani da gado, muna amfani da extends kalmar maɓalli don bayyana cewa ƙaramin aji ya gaji daga babban aji.

Misali:

class Animal {  
  name: string;  
  
  constructor(name: string) {  
    this.name = name;  
  }  
  
  eat() {  
    console.log(this.name + " is eating.");  
  }  
}  
  
class Dog extends Animal {  
  bark() {  
    console.log(this.name + " is barking.");  
  }  
}  
  
const dog = new Dog("Buddy");  
dog.eat(); // Output: "Buddy is eating."  
dog.bark(); // Output: "Buddy is barking."  

A cikin misalin da ke sama, Dog ajin ya gaji daga Animal aji kuma ya tsawaita ta hanyar ƙara bark() hanyar. Ajin Dog na iya amfani da eat() hanyar da aka gada daga Animal ajin.

 

Hanyoyin sadarwa

Hanyoyin sadarwa a cikin TypeScript ma'anar saitin kaddarori da hanyoyin da abu dole ne ya bi su. Suna ƙayyadad da kwangila don abubuwan da ke raba abubuwan gama gari.

Don amfani da musaya, muna amfani da interface kalmar maɓalli don ayyana abin dubawa.

Misali:

interface Shape {  
  calculateArea(): number;  
}  
  
class Circle implements Shape {  
  radius: number;  
  
  constructor(radius: number) {  
    this.radius = radius;  
  }  
  
  calculateArea() {  
    return Math.PI * this.radius * this.radius;  
  }  
}  
  
const circle = new Circle(5);  
console.log(circle.calculateArea()); // Output: 78.53981633974483  

A cikin misalin da ke sama, Shape mahaɗin yana bayyana calculateArea() hanyar da kowane abu dole ne ya bi. Ajin Circle yana aiwatar da Shape haɗin gwiwa kuma yana ba da aiwatarwa don calculateArea() hanyar.

 

Fa'idodin gado da mu'amala a cikin haɓaka aikace-aikace:

• Gado yana sauƙaƙe sake amfani da lambar kuma yana rage kwafi. Lokacin da ƙaramin aji ya gaji daga babban aji, zai iya sake amfani da kaddarorin da hanyoyin da aka riga aka aiwatar a cikin babban aji.
• Hanyoyin sadarwa suna bayyana kwangiloli kuma suna tilasta bin ƙayyadadden mu'amala, tabbatar da cewa abubuwa sun cika ka'idojin da ake buƙata. Suna kafa tsarin gama gari don haɓakawa da amfani da abubuwa.
• Dukansu gado da mu'amala suna ba da gudummawa ga sassauƙa a ƙira da haɓaka aikace-aikace, ba da damar ra'ayoyi kamar polymorphism da sake amfani da lambar.

 

A taƙaice, gado da mu'amala sune mahimman ra'ayoyi a cikin TypeScript. Suna taka muhimmiyar rawa wajen haɓaka aikace-aikacen, haɓaka sake amfani da lambar, sassauƙa, da bin ƙayyadaddun kwangila.
