Currying Currying simply means evaluating functions with multiple arguments and decomposing them into a sequence of functions with a single argument.  In other terms, currying is when a function ,instead of taking all arguments at one time, takes the first one and returns a new function, which takes the second one and returns a new function, which takes the third one, etc. until all arguments are completed. // Noncurried version const add = ( a , b , c ) => {   return a + b + c ; }; console. log ( add ( 2 , 3 , 5 )); // 10 // Curried version const addCurry = ( a ) => {   return ( b ) => {     return ( c ) => {       return a + b + c ;     };   }; }; console. log ( addCurry ( 2 )( 3 )( 5 )); // 10 There are several reasons why currying is ideal: Currying is a checking method to make sure that you get everything you need before you proceed It helps you to avoid passing the same variable again and agai...

Prototype Property In JavaScript, every function and object has a property named prototype by default.  All JavaScript objects inherit properties and methods from a prototype . If you want to add a new property or method to an existing object constructor you cannot add it dynamically,you'll have to add it to the constructor function itself. In JavaScript, a 'prototype' can be used to add properties and methods to a object constructor function. NOTE : The  Prototype property is used to provide additional properties to all the objects created from a constructor function. When you create a variable or function in javascript you automatically get acess to some in-built properties and methods,this is possible because Javascript adds those in-built properties/methods to the prototype object directly. Example function  Person(first, last, age, eyecolor) {    this . firstName  = first;    this . lastName  = last;    this . age  = age;...
