// 1773. Count Items Matching a Rule

// You are given an array items, where each items[i] = [typei, colori, namei] describes the type, color, and name of the ith item. You are also given a rule represented by two strings, ruleKey and ruleValue.

// The ith item is said to match the rule if one of the following is true:

// ruleKey == "type" and ruleValue == typei.
// ruleKey == "color" and ruleValue == colori.
// ruleKey == "name" and ruleValue == namei.
// Return the number of items that match the given rule.

var countMatches = function(items, ruleKey, ruleValue) {
    let keys = {
        "type": 1,
        "color": 2,
        "name": 3
    }
    for(let i = 0; i<items.length; i++) {
        for (let j = 0; j<3; j++) {
            if(items[i][keys.])
        }
    }
    
};

let items = [["phone","blue","pixel"],["computer","silver","lenovo"],["phone","gold","iphone"]]
let ruleKey = "color"
let ruleValue = "silver"
