We are required to write a JavaScript function that takes in two comma separated strings. The first string is the key string and the second string is the value string, the number of elements (commas) in both the strings will always be the same.
Our function should construct an object based on the key and value strings and map the corresponding values to the keys.
Example
const str1= '[atty_hourly_rate], [paralegal_hourly_rate], [advanced_deposit]'; const str2 = '250,150,500'; const mapStrings = (str1 = '', str2 = '') => { const keys = str1.split(',').map( (a) => { return a.slice(1, -1); }); const object = str2.split(',').reduce( (r, a, i) => { r[keys[i]] = a; return r; }, {}); return object; }; console.log(mapStrings(str1, str2));
Output
And the output in the console will be −
{ atty_hourly_rate: '250', paralegal_hourly_rate: '150', advanced_deposit: '500' }
