How to Check if a Value is Within a Range of Numbers in JavaScript

We can use the JavaScript’s greater than or equal to and less than or equal to operators to check if a number is in between 2 numbers.

const between = (x, min, max) => {
  return x >= min && x <= max;
// ...
const x = 0.002
if (between(x, 0.001, 0.009)) {
  // something
Enter fullscreen mode Exit fullscreen mode

We create the between function with the x , min and max parameters.


x is the number we want to check if it’s between min and max .

Then we call it in the if statement to see if x is between 0.001 and 0.009.
