  or it can be of another type like string or array which can be evaluated as "truthy" / "falsy".

// Independent check
if (myVar) {
	// entered if myVars value is either a boolean of value "true" or a value evaluated as "truthy"
}

// true/false check
if (typeof myVar === "boolean" && myVar) {
	// entered if myVars value is an actual boolean and if this boolean is "true"
}

// truthy/falsy check
if (typeof myVar !== "boolean" && myVar) {
	// entered if myVars value is not an actual boolean but if it's evaluated as "truthy"
