function test(n) {
    let y = 0
    let x = y / 2

    while (y < n) {
        console.log('add');
        y++;
    }
    console.log(y);
    console.log(x);
}
test(6);
//x prints out 0 instead of 3

x is supposed to change as y changes. How do I keep these variables synchronized?


If you want to keep the variables in sync all the time, you can create an object having y and a getter method for x which returns the value dependent on current value of y

let obj = {
  y: 0,
  get x() {
    return this.y / 2;
  }
};
function test(n) {
  while (obj.y < n) {
    console.log("add");
    obj.y++;
  }
  console.log(obj.y);
  console.log(obj.x);
}
test(6);

Objective Physics, (b) Variables : A quantity which can take up different values is called a variable quantity. A variable is usually represented as x, y, z etc. y=l+2+l+l=5 \3 , o o2 Keeping x = 1, and Keeping x =2, y=(2)J + 2x2z +2 + 1=19 Thus y changes on changing the value of x. The value of function y depends on the value of variable x. The independent variable varies along the x-axis of the cartesian plane, and the dependent variable varies along the y-axis. These variables are “x” and “y,” respectively. The value of y depends on x. When x changes, the “y” either increase or decrease. There are two types of Linear Regression. Simple Linear Regression


There's nothing that does that automatically, you need to do it yourself.

    while (y < n) {
        console.log('add');
        y++;
    }
    x = y/2;

If the second variable is always the same function of the first variable, are you sure you need two variables?

Causation and Explanation, and accordingly changes any variables whose values depend on the value of X for the assigned values to the zero-indegree variables. X can influence Y if  A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y y y y is often the variable used to represent the dependent variable in an equation. Example:


In general, your best option will likely be to use a function to calculate the value when it's called, particularly if you're doing inexpensive calculations. Think of it as an algebraic expression.

Consider the following:

function x(y) {
  return y / 2
}

function test(n) {
    let y = 0

    while (y < n) {
        console.log('add');
        y++;
    }
    console.log(y);
    console.log(x(y));
}
test(6);

Information Theory and Artificial Intelligence to Manage , (3.1) i=1,n in which H is a measure of information, choice and uncertainty. to (​E2) in that subtle changes in balance do not cause much change in uncertainty. When entropy is applied to a random variable (X,Y) whose values are in the set {(x, y), x; The reason for this is that its value depends on the choice of symbolic​  relationship between two variables (i.e. X and Y) and 2) this relationship is additive (i.e. Y= x1 + x2 + …+xN). Technically, linear regression estimates how much Y changes when X changes one unit. In Stata use the command regress, type: regress [dependent variable] [independent variable(s)] regress y x. In a multivariate setting we type:


If x is always half of y, then why do you need X?

Century Dictionary and Cyclopedia: Including Atlas of the World , In math., a mathematical quantity whose value depends upon the values of other of the variables; so that, if y is a function of r, there must be some value which y can But other writers hold that two quantities which are functions of a third are the values of a and y, so that in the course of any continuous change of x the  The controlled variables were the type of dish soap, amount of hydrogen peroxide, and the level of temperature. Also, write a correctly formatted hypothesis. The dependent variabl

In chapter 6 we know interaction term can be used to allow the marginal effect of X to depend on another regressor. The regression with both dummy and interaction term of dummy and X is Y = 0 + 1D + 2X + 3(X D)+u (16) which can be rewritten as Y = { 0 + 2X +u; when D = 0


Farrow's Military Encyclopedia: A Dictionary of Military Knowledge, The materials recommended for the purpose are brimstone with sawdust ; or are combined with constants in an equation, and are such that a change of value of value of one or more of the others, then such variables are said to depend on Thus, x- -\-y* — r* = 0 is an implicit function of two variables, but y = \'r- — x'1 is  dependent variable: A dependent variable is a variable whose value depends upon independent variable s. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation. The dependent variable is sometimes called "the outcome variable."


Dependent and independent variables review (article), A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. Posted 6 months ago. this would make x the independent variable since it is the one that would change and not determine which variable should be x and which should be y, if y is not dependent on x? if x is the independent variable and y is the dependent variable, then y= f(x) where f names the function
