Strict string comparison

What should you do if there are two values of different types, and you do not want to rely on automatic type conversion? You can convert them explicitly.

For example, you can cast a numeric value to a string type. One way is to use the number.toString() command. For example:

var number = 1;

// Logs number: 1 (number)
console.log(number);

// Logs string: "1" (string)
console.log(number.toString());

script.js

JavaScript

var string = '123'; var number = 123; if (string == number) { console.log('The values are equal!'); } else { console.log('The values are not equal.'); }

Let’s convert the second value to a string.

Replace == with === in the condition. Strict equality does not convert types, so the condition will be false.
Replace number in the condition with number.toString(). Both values are now strings, so the condition should be true.
