JavaScript Truthy and Falsy

JavaScript does type conversion when evaluating various data types in Boolean contexts. For example:

const jedi = "Skywalker"
const name = jedi ? jedi : "No name"

The name variable will be have Skywalker string as its value because the jedi was evaluated as truthy. Other type of coercion, falsy, also happens when non Boolean data types which identified as false evaluated in Boolean context, for example:

const jedi = ""
const name = jedi ? jedi : "No name"

In the example above the name variable value will be No name because the jedi was evaluated as false.

Examples of other truthy values:

if (true)
if ({})
if (\[\])
if (42)
if ("0")
if ("false")
if (new Date())
if (-42)
if (12n)
if (3.14)
if (-3.14)
if (Infinity)
if (-Infinity)

Examples of falsy values

if (false)
if (null)
if (undefined)
if (0)
if (0n)
if (NaN)
if ('')
if ("")
if (\`\`)
if (document.all)
