javascript - json reorganization problem, more complicated

Question

1. Question: Convert json1 to json2 form
2. Description: There may be infinite layers in properties, type refers to the type, the array type has items, and the array may be an object array or other types.
json1:

Due to time constraints, I didn’t write too much details in the comments

    // 假设 a 就是json1， b 就是json2
    var a = {
        body: {...}
    };
    var b = {
        body: {...}
    };

    function recursion( data, o, type ) {
        // 这里规定下，最终递归出来的数据类型
        b.body[o] = {
            'object': {},
            'array' : [],
            'string': ''
        }[ type ];
        
        // 这里获取下面的新数据，
        var newData = {
            'object': data.properties,
            'array' : data.items,
            'string': data.description
        }[ data.type ];
    
        //　判断新数据是否符合递归条件，并获得最终数据
        if ( newData && newData.type ) {
            recursion( newData, o, type )
        }else{
            if ( type == 'object' || type == 'array' ) {
                for (let i in newData){
                    newData[i] = newData[i].description
                }
            };

            if ( type == 'array' ) {
                b.body[o].push(newData);
            } else {
                b.body[o] = newData;
            };
        };
    }

    var data = a.body.properties;
    for (let o in data) {
        // 从这里开始递归，
        recursion( data[o], o, data[o].type )
    }
    console.log(b);

Tree recursive traversal is fine.

Thanks for the invitation. . . .

function deepReadTree(param) {
        var child_param, cur_result;
        if (param.properties) {
            child_param = param.properties;
            cur_result = {};
            for (var key in child_param) {
                cur_result[key] = deepReadTree(child_param[key]);
            }
        } else if (param.items) {
            child_param = param.items.properties;
            cur_result = {};
            for (var key in child_param) {
                cur_result.push(deepReadTree(child_param[key]));
            }
        }else{
            cur_result = param.description;
        }

        return cur_result;
    }

Logically speaking, your items should be an array, otherwise your data structure cannot be produced.
