Lazy simple explanation pretty awesome : Credit to https://agrawalsuneet.github.io/blogs/lazy-property-in-kotlin/

	private const val SALARY_THRESHOLD = 100

	private val taxCollector = TaxCollector()

	//before using lazy
	private val accountant = Accountant()

	//after using lazy everything by the keyword is delegate, this lazy is used when we want to utilize account
	private val accountant by lazy {

Kotlin Collection Functions best use of function simplifying the Array List List good use of List Array and Set Map, use inline and predicate to filter list and the Unzip is soo cool some functions associateBy toSet joinToString reduce partition sorted all groupBy zip filter union single and if you have a very large collection list of data

	//***********removing the duplicate strings from an array*****************
	// Maintain the original order of items
	val devs = arrayOf("Amit", "Ali", "Amit", "Sumit", "Sumit", "Himanshu")
	print(devs.distinct()) // [Amit, Ali, Sumit, Himanshu]

	// Maintain the original order of items
	val devs = arrayOf("Amit", "Ali", "Amit", "Sumit", "Sumit", "Himanshu")
	print(devs.toSet()) // [Amit, Ali, Sumit, Himanshu]
