Introduction

In ES6, the concept of truthiness is an important concept to understand. It is a concept that determines whether a value is considered true or false. In this article, we will discuss whether 0 is considered true in ES6. We will look at the different ways that 0 can be evaluated and how it is treated in ES6. We will also discuss the implications of this evaluation and how it can affect your code. By the end of this article, you should have a better understanding of how 0 is treated in ES6.

Solution

No, 0 is not considered true in ES6. In ES6, only values that are truthy (i.e. any value other than false, 0, null, undefined, NaN, or an empty string) are considered true.


This is a list of all falsy values in javascript:

  • false
  • 0
  • ” or “”
  • null
  • undefined
  • NaN

Only the String ” is a falsy value, meaning that it is an empty string.
‘0’ is a string with content so it isn’t a falsy value, but 0 is one.

solved Is 0 considered true in ES6?


The answer to the question “Is 0 considered true in ES6?” is No. In ES6, 0 is considered falsey, meaning it is not considered true. This is because 0 is a falsy value, meaning it evaluates to false when used in a boolean context. Other falsy values include null, undefined, NaN, empty strings, and false.

In ES6, the Boolean() function can be used to convert a value to a boolean. If the value is 0, it will be converted to false. For example:

let x = 0;
let y = Boolean(x);
console.log(y); // false

In addition, the logical operators && and || can be used to evaluate a value as true or false. If the value is 0, it will be evaluated as false. For example:

let x = 0;
let y = x && true;
console.log(y); // false

In conclusion, 0 is not considered true in ES6.
