building_strings_from _hash.js

// Description:
// // Complete the solution so that it takes the object (JavaScript/CoffeeScript) or hash (ruby) passed in and generates a human readable string from its key/value pairs.
// // The format should be "KEY = VALUE". Each key/value pair should be separated by a comma except for the last pair.
// // Example:
// // solution({a: 1, b: '2'}) // should return "a = 1,b = 2"

// SOLUTION:

function solution(pairs) {
    let result = '';
    for (let key in pairs) {
        result += `${key} = ${pairs[key]},`

    }
    return result.slice(0, -1);
}
