Nullability is important, collections are different, and classes are final default. Kotlin is more functional, but what does that mean, and how should it change the way that you program? And what about all that Java code that you still have to support? Your tour guides Duncan and Nat first made the trip in 2015, and they've since helped many teams and individuals follow in their footsteps. Travel with them as they break the route down into legs like Optional to Nullable, Beans to Values, and Open to Sealed Classes.

My fave!!
Size: 6 Fl Oz (Pack of 1)
Wow. I'm so impressed with this conditioner that I'd pay three times what it cost, but I'm glad it's so reasonably priced! For reference, I bought this for myself, not a child, and my hair is medium-fine, wavy, and just past my shoulders. My hair is in good condition since I gave up heat styling a few months ago, starting using more organic hair products, and also switched from chemical hair color to using pure henna. But even though my scalp is oily, my hair is on the dry side because it's still recovering from the abuse I used to put it through, plus I live in the desert. So I like a rich conditioner that deeply moisturizes my hair, and this one does that better than any other conditioner I've ever tried, and I've tried SO SO many. My hair feels hydrated and silky after using this, and shines like crazy in the sunlight. The same day I used it, my husband commented "Your hair looks so healthy." This conditioner also brings out my waves and reduces frizz, without feeling or looking heavy... but a little goes a LONG way... this is a serious conditioner, not a watered-down drugstore product. So if you over-do it, your hair may go limp. I can't stand perfume-y smelling hair products, so I'm happy to say the aroma is natural, and while I wouldn't call it "light," it's certainly not strong. I really love the scent and would describe it as warm and comforting. I hope they never stop making this stuff. It reminds me of another conditioner I really like, by Accure, but I have to say I like the results and aroma of this one even better.

Very useful for babies
Size: 6 Fl Oz (Pack of 1)
This is a must buy. I bought this for my son who has hypersensitivity. A little bit goes a long way and it is very concentrated. The scent is not nauseating. It washes off well and is definitely worth the price.

Extremely nourishing and moisturizing
Size: 6 Fl Oz (Pack of 1)
Really like this conditioner for my daughter. It leaves her hair so soft after using, I use to use shea moisture kids conditioner on her hair and it would never feel silky or smooth after a shower. This conditioner definitely makes it feel nourished. I also love that it’s vegan. really good for your kids hair. I recommend it! As previous reviews states it has a bad scent, I don’t think so at all. The scent is just more natural. It’s not sweet and fake like these other conditioners. Love the product!

Love this conditioner
Size: 6 Fl Oz (Pack of 1)
We LOVE this conditioner. It's just the right amount of moisture for our kids' hair. Even does the trick after swim lessons in a pool with chlorine. Smells great without smelling toxic or perfumey. Tangles come right out.
