Is it truthy or falsy value, let number = "false";

  • Share this:

In JavaScript, the value "false" is a string, not a boolean. In JavaScript, the boolean values are `true` and `false`, and the string value "false" is considered a truthy value. This means that if you were to use "false" in a boolean context, such as in an `if` statement, it would be evaluated as `true`.

Here is an example to illustrate this:

let number = "false";

if (number) {
  console.log("The value is truthy");
} else {
  console.log("The value is falsy");

The output of this code would be "The value is truthy", because the string "false" is a truthy value.

If you want to test for a boolean value of `false`, you can use the `===` operator to test for strict equality, like this:

let number = false;

if (number === false) {
  console.log("The value is false");
} else {
  console.log("The value is not false");

This code will output "The value is false" because the variable `number` is strictly equal to the boolean value `false`.
