Build LLVM / Clang on MacOS


Built-in Clang / LLVM shipped by Xcode does not support Leak Santizer (-fsantize=leak) feature. For example, this code has memory leak:

// File: main.c

#include <stdlib.h>

Event Loop
View async.jsx
// Async should be first priority over callbacks and promises
// High level idea:
// - Avoid .then .catch in promise
// - Syntatic sugar to make async programming similar to sequential code
const axios = require('axios');
async function getUser(id) {
let resp = await axios.get(`${DEFAULT_URL}/users/${id}`)
