A full node lets you access all state. There is a light node (state-on-demand) and wallet-only (no state) instructions as well,
var insertionSort = function (a) { | |
// Iterate through our array | |
for (var i = 1, value; i < a.length; i++) { | |
// Our array is split into two parts: values preceeding i are sorted, while others are unsorted | |
// Store the unsorted value at i | |
value = a[i]; | |
// Interate backwards through the unsorted values until we find the correct location for our `next` value | |
for (var j = i; a[j-1] > value; j--) { | |
// Shift the value to the right | |
a[j] = a[j-1]; |
function(array, value) { | |
var j = 0, length = array.length; | |
// A for loop was used to save space. More easily understood as a while loop. Exits if our pointer moves out of range. | |
while (j < length) { | |
var i = (length + j - 1) >> 1; // move the pointer to the median value using a shift in place of Math.floor() (to save characters) | |
// If the value we're searching for is greater than the median, move our lower-bound past the median | |
if (value > a[i]) | |

// Otherwise, if the value we're searching for is less than the median, move our upper-bound to the median value | |
else if (value < array[i]) |

Say we have a prop.users of the shape:
const users = [
{username: 'bob', age: 30, tags: [{name: 'work', id: 1}, {name: 'boring', id: 2}]},
{username: 'jim', age: 25, tags: [{name: 'home', id: 3}, {name: 'fun', id: 4}]},
{username: 'jane', age: 30, tags: [{name: 'vacation', id: 5}, {name: 'fun', id: 4}]}
];
