6. Make a Dictionary from Fundamentals with JS

Здравейте, колеги!

Много ми се ще да направя това решение по-декларативно с помощта на reduce, map, filter и да избегна , доколкото е възможно for - циклите.

Ще се радвам, ако някой редактира това решение или просто ми даде насоки!

Задача: You will receive an array with strings in the form of JSON's.

You have to parse these strings and combine them into one object. Every string from the array will hold terms and a description. If you receive the same term twice, replace it with the new definition.

Print every term and definition in that dictionary on new line in format:

`Term: ${term} => Definition: ${definition}`

Don't forget to sort the dictionary alphabetically by the terms as in real dictionaries.

Examples

;-)

function solve(arr) {
    // let copy = [];
    // let obj = {};

    // for (let element of arr) {
    //     let converted = JSON.parse(element);
    //     if (typeof converted === 'object') {
    //         for (let key in converted) {
    //             obj[key] = converted[key];
    //         }
    //     }

    // }
    // for (let key in obj) {
    //     copy.push(`Term: ${key} => Definition: ${obj[key]}`)

    // }

    let array = input.reduce((acc, curr, i) => {
        let term = Object.keys(JSON.parse(curr))[0];
        let text = Object.values(JSON.parse(curr))[0];
        acc.push({ [term]: text });

        return acc;
    }, []);

    let copy = array
        .sort((a, b) => Object.keys(a)[0].localeCompare(Object.keys(b)[0]))
        .map((el) => {
            return `Term: ${Object.keys(el)[0]} => ${Object.values(el)[0]}`;
        })
        .join('\n');

    return copy;
}

Още един въпрос - как да получим масив, в който term  да не се повтаря и да получим последната дефиниция на съответния term??
