Feeling confident in Javascript? Well, given a string of lowercase letters, would you be able to sum them all up into 1 value? In one line of code? Solution and explanations are below. 1/6🧵👇

UPDATE: We still don’t know Lucero’s whereabouts. I want to personally say thank you to everyone who’s reposted, said a prayer, and especially those who have went to higher attempts of finding my friend🖤I’ll be posting updates and ways you can #helpfindlucero on my twitter.

And that's it! So in summary, we - split the string into characters - go through each character, converting it into a number - Sum up all the numbers Thanks for sticking around, and stay tuned for the next js lesson.

> .reduce((a, b) => a + b, 0); Lastly, this reduces the list down to a single value. It calls the function we pass on each item in the array, storing the result and calling it again with the next value in the array. Here we are summing up every element in the list.

> .map(c => c.charCodeAt(0) - 96) Map accepts a function and will return the array created from calling the function on every element in the array. Here we are going through our array of characters, and turning each one into a digit, subtracting 96 so a=0. 6/6🧵👇

So what does 's.split('')' do? Well, split() is a string method, that will divide the string into substrings, and returns them as an array. In this case, '' means we want to divide the string at every character. This gives us the string as an array of characters 5/6🧵👇

> s > .split('') This is the same as `s.split()` However, JS ignores newlines (line-terminators) when they separate bits of code (except in cases where it auto-inserts ';' like in return) We do this so as we chain multiple functions, it stays easy to read 4/6🧵👇

> 'const lettersum = s =>' First, we use 'const' to declare a variable (named 'lettersum') whose value shouldn't change later. Then we begin to declare a function using a compact definition called an 'arrow function expression'. 3/6🧵👇

const lettersum = s => s .split('') .map(c => c.charCodeAt(0) - 96) .reduce((a, b) => a + b, 0); Pretty concise, isn't it? Let's go over this step-by-step 2/6🧵👇

Investment / Collector DAOs These let people pool capital with the aim of investing in specific assets, ranging from NFTs to sports franchises! This is a fast and simple alternative to venture capital funds. Examples are - PleasrDAO - MetaCartel Ventures - Komerabi 7/16🧵👇

Ex. Protocol DAO Some examples of Protocol DAOs are - Uniswap - Compound - Aave For example, Uniswap token holders voted on which Layer-2 networks the protocol should be deployed. 6/16🧵👇

Protocol DAOs From Ethereum came a whole array of new crypto assets. Protocols were made to let people trade these assets. DAOs then emerged to let users have a collective say in the future of the protocol. Voting is done with governance tokens given to users 5/16🧵👇

What do DAOs do? Present DAOs have a variety of missions, from: - Manage large protocols - Investment - Social Communities - Media - Philanthropic Pursuits Let's take a look at each category now 4/16🧵👇

What is a DAO? DAOs are software-enabled organizations. The industrial revolution favored the LLC as the tool to organize. DAOs will fulfill this role for Web3 at large. DAOs are leaner than LLCs, attracting talent from all over the world. 3/16🧵👇

Social networks (and the internet) have made it easy for like-minded individuals to congregate and communicate. The advent of crypto will likewise make it easy to coordinate around financial capital Internet <-> Communication DAOs <-> Capital 2/16🧵👇

Polkadot is a cryptocurrency network that wants to help weave all the disparate blockchains together. Currently, blockchains operate in silos, separately. But Polkadot promises to fix this by creating an internet of interoperable blockchains. 2/11🧵👇

Advantages of DAOs? 📖 Transparency - all actions viewable by anyone. 🔥 Global power - anyone anywhere can contribute 💵 Cheaper - tools can be used like Legos, so little needs to be built from scratch. 👨‍👩‍👦‍👦 Collaborative - giving everyone a voice pools mass knowledge 5/13🧵👇

How do DAOs work? - Governance mechanism is provided by the smart-contracts - Governance tokens are used by members to vote on actions taken by the DAO - more contributed = stronger vote - Outcome can also be based on participation 4/13🧵👇

In more detail, a DAO is an organization with control spread out amongst member, vs top-down. They are organized with smart-contracts, and members use 'governance tokens' to vote on decisions made by the DAO. The DAO then executes these decisions, like a machine. 3/13🧵👇
