Is there a way to search a console logged object for particular values in Chrome DevTools?

Question

I'd like to console.log() an object and do a search for a particular value within that object. Is this possible?

Note: the object that I'm trying to search is humongous and multi-dimensional, so expanding each field and doing a simple Ctrl+F find isn't ideal.

The code below adds something like what you're looking for to the console object as

console.logSearchingForValue

Breadth-first search, matching on equivalent "JSON" value, handling NaNs correctly, returning multiple locations, and making numeric index expressions not quoted are left as exercises to the reader. :)

It is already really easy to swap in different definitions of equality.

var searchHaystack = function(haystack, needle, path, equalityFn, visited) {    if(typeof haystack != "object") {     console.warn("non-object haystack at " + path.join("."));   }    if(visited.has(haystack))     return [false, null];    for(var key in haystack) {     if(!haystack.hasOwnProperty(key))       continue;      if(equalityFn(needle, haystack[key])) {       path.push(key);       return [true, path];     }      visited.add(haystack);     if(typeof haystack[key] == "object") {       var pCopy = path.slice();       pCopy.push(key);       var deeper = searchHaystack(haystack[key], needle, pCopy, equalityFn, visited);       if(deeper[0]) {         return deeper;       }     }   }   return [false, null]; }  var pathToIndexExpression = function(path) {    var prefix = path[0];    path = path.slice(1);    for(var i = 0; i < path.length; i++) {       if(typeof path[i] == "string")          path[i] = "\"" + path[i] + "\"";    }    return prefix + "[" + path.join("][") + "]" }  console.logSearchingForValue = function(haystack, needle) {    this.log("Searching");    this.log(haystack);    this.log("for");    this.log(needle);    var visited = new Set();    var strictEquals = function(a,b) { return a === b; };    var result = searchHaystack(haystack, needle, ["<haystack>"], strictEquals, visited);    if(result[0]) {       this.log("Found it!");       this.log(pathToIndexExpression(result[1]));    }    else {       this.log("didn't find it");    } }
