Benchmark: Object vs array performance 2

Tests:

Object
const node_type_html = 1; const node = {}; node.type = node_type_html; node.tag = 'div'; node.children = []; node.attrs = {}; const nodeType = node.type; const nodeTag = node.tag; const nodeChildren = node.children; const nodeAttrs = node.attrs;
Array with constants
const node_index_type = 0; const node_index_tag = 1; const node_index_children = 2; const node_index_attrs = 3; const node_type_html = 1; const node = []; node[ node_index_type ] = node_type_html; node[ node_index_tag ] = 'div'; node[ node_index_children ] = []; node[ node_index_attrs ] = {}; const nodeType = node[ node_index_type ]; const nodeTag = node[ node_index_tag ]; const nodeChildren = node[ node_index_children ]; const nodeAttrs = node[ node_index_attrs ];
Array with inline numbers (post-minification)
const node_type_html = 1; const node = []; node[ 0 ] = node_type_html; node[ 1 ] = 'div'; node[ 2 ] = []; node[ 3 ] = {}; const nodeType = node[ 0 ]; const nodeTag = node[ 1 ]; const nodeChildren = node[ 2 ]; const nodeAttrs = node[ 3 ];
Inline object
const node_type_html = 1; const node = { type: node_type_html, tag: 'div', children: [], attrs: {} }; const nodeType = node.type; const nodeTag = node.tag; const nodeChildren = node.children; const nodeAttrs = node.attrs;
inline array
const node_type_html = 1; const node = [ node_type_html, 'div', [], {} ]; const nodeType = node[ 0 ]; const nodeTag = node[ 1 ]; const nodeChildren = node[ 2 ]; const nodeAttrs = node[ 3 ];
