lazy VS lateinit

lateinit var whereas lazy val

A lateinit property can be reinitialized, but lazy property an only be initialized once.
lateinit can’t have custome getter and setter whereas lazy has custom getter

A lazy property has a block executed the first time that property is called.
Primitive types

lateinit properties can’t be of primitive types, but lazy properties can.

Thread safety

We can’t define thread safety in lateinit, but we can define in case of lazy.

 val lazyUser : User? by lazy(LazyThreadSafetyMode.SYNCHRONIZED) {
         User(id = 1, username = "agrawalsuneet")
     }
