Convert truthy falsy to boolean | Javascript

 const myVar = null; 
const mySecondVar = 1; 

console.log( Boolean(myVar) ) // false
console.log( !!myVar ) // false


console.log( Boolean(mySecondVar) ) // true
console.log( !!mySecondVar ) // true 

AI Explanation

This code snippet demonstrates the concept of type coercion in JavaScript. The `Boolean()` function and the double negation operator `!!` are used to convert values to boolean type. 1. `myVar` is assigned the value `null`. When using `Boolean(myVar)`, the `Boolean()` function coerces the value to a boolean. Since `null` is a falsy value, the output is `false`. Similarly, the double negation operator `!!myVar` also coerces `myVar` to a boolean, resulting in `false`. 2. `mySecondVar` is assigned the value `1`. When using `Boolean(mySecondVar)`, the `Boolean()` function coerces the value to a boolean. In JavaScript, any non-zero number is considered a truthy value, so the output is `true`. Similarly, the double negation operator `!!mySecondVar` also coerces `mySecondVar` to a boolean, resulting in `true`. In summary, the code showcases how `Boolean()` function and double negation `!!` can be used to convert values to boolean type for logical operations in JavaScript.
