// Implement a min heap:

// -> insert, extract_min

// property: 
// - elements are in ascending order
// - complete binary tree (node is smaller than it’s children)
// - root is the most minimum
// - insert takes O(logn) time
//     - insert to the bottom right

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
