Piping Function

 What is a piping function ?

The result of one function will be the argument of another function.

Normal code --->

  const val ={
   salary:10000
}

const getSalary =(person)=> person.salary; 
const addBonus = (netSalary)=>netSalary+1000;
const deductTax=(grossSalary) =>{
  const percentDeduction =grossSalary * 0.3
  return grossSalary - percentDeduction
}

const pipe = (getSalary,addBonus,deductTax)=>{
  return (val)=>{
    const person=val;
    const netSalary=getSalary(person);
    const grossSalary =addBonus(netSalary);
    const CreditSalary = deductTax(grossSalary);
  
  return CreditSalary;  
  }
}



const result =pipe(getSalary,addBonus,deductTax)(val);

console.log(result)

PIPING CODE

  const val ={
   salary:10000
}

const getSalary =(person)=> person.salary; 
const addBonus = (netSalary)=>netSalary+1000;
const deductTax=(grossSalary) =>grossSalary - (grossSalary * 0.3)


const pipe = (...fns)=>{
  return (val)=>{
    fns.forEach((fn)=> val=fn(val))
  
  return val;  
  }
}



const result =pipe(getSalary,addBonus,deductTax)(val);

console.log(result)

const obj ={
  a:{
    b: (a,b,c)=> a+b+c,
    c: (a,b,c)=> a+b-c,
  },
  d :(a,b,c)=> a-b-c
}



const pipe =(obj)=>{
  
  return (...args)=>{
    for( let key in obj){
    let val =obj[key];
    
    if(typeof val==='function'){
      obj[key] =val(...args);
    }
    else{
      obj[key]=  pipe(val)(...args)
    }
    }
    return obj;
  }
}



console.log(pipe(obj)(1,1,1));
