Method chaining, or simply chaining, in JavaScript can be defined as when one or more sequential methods get invoked from an object without the introduction of unnecessary variables. The sole purpose of chaining is to make our code more readable and reduce the redundancy within.
Each object has a private property which holds a link to another object called its prototype. That prototype object has a prototype of its own, and so on until an object is reached with null as its prototype. By definition, null has no prototype, and acts as the final link in this prototype chain.
Each method in chaining returns an object. It violates the need for intermediate variables. In other words, the method chaining can be defined as if we have an object and we call methods on that object one after another is called method chaining.
I have a bunch of useful functions that I have collected during my whole life.
function one(num){
return num+1;
}
function two(num){
return num+2;
}
I can call them with two(two(one(5)))
But I would prefer to use (5).one().two().two()
How can I achieve this without using prototype?
I tried to see how underscore chain works, but their code is too intense to understand it
