I am trying to call a function does multiplication On another function that accepts two numbers as parameters. i Have tried using constructor and nested function, but to no avail. i have tried the followings:

function Coordinate(a, b) {
    var x, y;
    return {x: a, y: b};
    function multiply(n) {
       x * n;
       y * n;
    }
}
var makeCoordinate = new Coordinate(2,3);
console.log(makeCoordinate.multiple(2));

// expected output: 4 6;


You should set multiply to be on the Coordinate's prototype so that when you call new Coordinate, the instantiated object will have multiply as a method. For it to work, you should also set this.x and this.y instead of returning an object directly:

function Coordinate(a, b) {
  this.x = a;
  this.y = b;
}
Coordinate.prototype.multiply = function(n) {
  this.x *= n;
  this.y *= n;
  return this;
}
var makeCoordinate = new Coordinate(2,3);
console.log(makeCoordinate.multiply(2));

6.6. Functions can Call Other Functions, Now we will look at another example that uses two functions. To draw a rectangle we need to be able to call a function with different arguments for width and  I am giving an example here. The below first function calls a seconds function to calculate the sum of three numbers. This is the second function which calculates sum of two numbers.


The answer modified two parts:

  1. the creation of Coordinate members
  2. multiple -> multiply

Hope this help :)

function Coordinate(a, b) {
    this.x = a;
    this.y = b;
    this.multiply = function(n) {
       return this.x * n + " " + this.y * n;
    }
}
var makeCoordinate = new Coordinate(2,3);
console.log(makeCoordinate.multiply(2));

Calling one function from another - function scope, I am sure this is blindingly obvious but How does one call a function from a second function? If 'nested' within the current function it is fine  In Python, any written function can be called by another function. Note that this could be the most elegant way of breaking a problem into chunks of small problems. In this article, we will learn how can we call a defined function from another function with help of multiple examples. Calling and Called Function ?


Well, firstly your console.log is calling multiple, not multiply.

Second, try an approach like this:

function Coordinate( a, b )
{
   function multiply( n ) 
   {
      this.x = this.x * n;
      this.y = this.y * n;
      return this;
   }
   var co = { x: a, y : b };
   co.multiply = multiply.bind( co );
   return co;
}

How to call a function that return another function in JavaScript , The task is to call a function which returns another function with the help of JavaScript. we're going to discuss few techniques. Approach: First call the first  In this tutorial, we will learn how to call a function from another function in Python. Let’s focus on the definition of a function. Certainly, a function consists of a set of statements to perform a specific task. This is how a function looks like. So, in the first step, there are two sample functions namely fun1 ( ) and fun2 ( ).


Having clarified in the comments, the (simplest)solution is:

// important code
function Coordinate(a,b) {
    this.x = a;
    this.y = b;
    this.multiply = function (n) {
        this.x = this.x*n;
        this.y = this.y*n;        
    }
}

// test code
let coord = new Coordinate(2,3);
console.log("Original Coordinate:");
console.log(coord);
    
coord.multiply(2);
console.log("Changed Coordinate: ");
console.log(coord);

Python - Call function from another function, In this article, we will learn how can we call a defined function from another function with help of multiple examples. Calling and Called Function ? The Function  do.call constructs and executes a function call from a name or a function and a list of arguments to be passed to it. either a function or a non-empty character string naming the function to be called. a list of arguments to the function call. The names attribute of args gives the argument names. a logical value indicating whether to quote


JavaScript Function Invocation, The code inside a function is executed when the function is invoked. It is common to use the term "call a function" instead of "invoke a function". It is also common  I need to write a script that creates and calls a function named fnItemTotal that calculates the total amount of an item in the OrderItems table (discount price multiplied by quantity). To do that, this function should accept one parameter for the item ID, it should use the DiscountPrice function that I created earlier and it should return the

If a function is not a method of a JavaScript object, it is a function of the global object (see previous chapter). The example below creates an object with 3 properties, firstName, lastName, fullName.

Omit the parentheses, list the arguments, and do not assign the function to a variable, as shown in the following example.
