JavaScript is a worldwide popular language that can make any web page interactive for users. When it comes to taking input from the user, this language plays an important role. There are multiple projects that developers and programmers use. Even beginners are also getting used to this language by trying basic projects so that they can go for the bigger web pages. They also want to check if a number is between two numbers in JavaScript.

To check if a number is between two numbers, you need to use the operators so that can also know how the operator works. Check out how to check if a Number is Between two numbers in JavaScript

How to Check if a Number is Between Two Numbers in JavaScript

We are going to use a few ways to check if a number is between two numbers in JavaScript

• To chain two conditions, we use &&(and) operator
• Check if the first condition has a greater number than the lower range, and the second number is lower than the higher range.
• The numbers are found to be in range if both conditions are met

Using && Operator

This operator is used to check if the two conditions are met, the number is greater than the lower value and the number is lower than the greater value. And for this, we also use the ‘if’ block. When both conditions are met, the number is in range, or else it isn’t.

Take a look at the code:

const value = 120.85;
const Minimum = 30.55;
const Maximum = 120.75;

if (value > Minimum && value < Maximum) {
  console.log('Value in allow limit');
} else {
  console.log('Value exceeds the allowable threshold');
}

Output:

Value exceeds the allowable threshold

The evaluation of the ‘&&’ operator starts from left to right. In this case, our ‘if’ statement returns ‘false’ for the first condition, the operator stops and doesn’t evaluate the second condition.

Number Evaluation Process

 In this process, we evaluate how conditions are met when we use the ‘if’ statement. Check the example

if (5 > 89 && 17 > 8) {
  // The command to do something.
}

Here, we have ‘17 > 8’ is the condition that never evaluated being the second condition. First, ‘5 > 89’ is checked and returns ‘false’, so the ‘&& operator stops there. Check a few more example of && operator to understand it better:

console.log(true && true); // true
console.log(false && false); // false
console.log(true && false); // false
console.log(false && true); // false
console.log('Ittutoria' && 'Js'); // 'Js'
console.log('Javascrift' && ''); // ''
console.log('' && 'Js'); // ''

In JavaScript, the falsy values are: ‘false’, ‘null’, ‘NaN’, ‘undefined’, ‘0’, and empty string.

In the above example, an empty string is used as the first value, and as an empty string is a falsy value, we get it in return when using the ‘&&’ operator. Like this

console.log('' && 'Js'); // ''

Conclusion

Here we talked about how to check if a number is between two numbers in JavaScript. Simple ways have been highlighted to help you get through the code.

I wish you luck for your project!
