Collect distances from 1 point to all others in a graph Problem:
I have a weighted graph. I want to get distance from definite point to all other points in the graph.(and then get path to them) 
I used modified dijkstra algorithm
So, here is code:
var get_path = function(graph, a) {
// declaration
let cache, i, v, queue, node, links, root,
    j, link, c, n, d, max, w, L = graph.length;

// initialization
cache = Array(L);
i = L;
while (--i &gt;= 0) {
    v = graph[i];
    cache[v.id] = {
        id: v.id,
        distance: Infinity,
        links: v.links,
        prev: null,
    };
}
root = cache[a];
root.distance = 0;
queue = [root];

// processing
i = 0;
while (i &lt; queue.length) {
    node = queue[i];
    links = node.links;
    j = links.length;
    while (--j &gt;= 0) {
        link = links[j];
        c = cache[link.id];
        d = node.distance + link.weight;
        if (d &lt; c.distance) {
            c.prev = node;
            c.distance = d;
            queue.push(c);
        }
    }
    i++;
}

return cache;
}

Graph format is:
graph = [
  {
    id: 1,
    links: [
      {
        id: 2,
        weight: 1,
      },
      {
        id: 3,
        weight: 1,
      },
    ],
  },
  {
    id: 2,
    links: [
      {
        id: 1,
        weight: 1,
      },
      {
        id: 4,
        weight: 2,
      }
    ]
  },
  {
    id: 3,
    links: [
      {
        id: 1,
        weight: 1,
      },
      {
        id: 4,
        weight: 3,
      }
    ]
  },
  {
    id: 4,
    links: [
      {
        id: 2,
        weight: 2,
      },
      {
        id: 1,
        weight: 1,
      },
      {
        id: 3,
        weight: 3,
      },
      {
        id: 5,
        weight: 1,
      }
    ]
  }, 
  {
    id: 5,
    links: [
      {
        id: 4,
        weight: 1,
      }
    ]
  }
]

Performance:
In my PC this algorithm works with graph of ~160 vertices and ~350 edges about 0.03-0.06ms. But I need faster!
You can measure performance on your PC here
Question:
How to make this code (function get_path()) faster? Is it possible on JavaScript? If I should change the format of graph to make algorithm faster it's not a problem.

Or I exhausted possibilities of JavaScript?
Interesting question;
Naming

The names are on the whole terrible, it really blocks the reading flow, the only good 1 letter variable is i
Further evidence of the bad naming is that I only realized that n, w, and max are never used because of jshint.com
JavaScript follows lowerCamelCase so get_path -&gt; getPath
In fact, even getPath would be a bad name, because you are not getting a path, getPaths could be better (you are getting more than 1 ), but getDistances or even getDistancesFromNode seems best

Declarations

You are mixing var and let in your code, I would stick to let and const

You are not declaring res at all (now it's a global) because this
var s_t = performance.now()
res = get_path(graph, 157)

should be
var s_t = performance.now(),
res = get_path(graph, 157)



Performance
This is already quite impressive, the only thing I noticed is that you process child nodes even if their child count is one (meaning really zero, since that 1 node must be the parent).
I assume the while loops are meant to be the fastest approach, however it seems that the fastest approach is now the most readable approach.
If you were allowed to just use/modify graph instead of cache it would be faster, of course the code reviewer would have told you that's not clean ;)
Comments
Comments should be meaningful, these comments are rather obvious.
All in all, if I had to maintain this, then I would rewrite with proper variable names but otherwise this is perfectly maintainable.


function getDistancesFromNode(graph, origin) {

  let cache, i, j, queue, node, links, root,
      link, nextNode, distance, nodeCount = graph.length;

  cache = Array(nodeCount);
  i = nodeCount;
  while (--i &gt;= 0) {
      node = graph[i];
      cache[node.id] = {
          id: node.id,
          distance: Infinity,
          links: node.links,
          prev: null,
      };
  }
  root = cache[origin];
  root.distance = 0;
  queue = [root];

  i = 0;
  while (i &lt; queue.length) {
      node = queue[i];
      links = node.links;
      j = links.length;
      while (--j &gt;= 0) {
          link = links[j];
          nextNode = cache[link.id];
          distance = node.distance + nextNode.weight;
          if (distance &lt; nextNode.distance &amp;&amp; nextNode.links.length &gt; 1) {
              nextNode.prev = node;
              nextNode.distance = d;
              queue.push(nextNode);
          }
      }
      i++;
  }
  return cache
};
