Description
The following pattern:
if (condition) {
return true
}
return false
can be refactored to:
return condition
When condition is not a boolean value,
it can be cast into one using the Boolean constructor.
Bad Practice
function isEven(num: number) {
if (num % 2 === 0) return true
return false
}
async function userExists(name: string) {
if (await db.getUser(name)) return true
return false
}
Recommended
function isEven(num: number) {
return num % 2 === 0
}
async function userExists(name: string) {
return Boolean(await db.getUser(name))
}
