JS-KATA: Zip Strings

Implement a zipStrings function in zip-strings.js with the following requirements in mind.

• The zipStrings function receives two string parameters
• The zipStrings function should return one string where the characters of both parameters are merged using the zip procedure (Reißverschlussverfahren)
• Merge the strings as shown in the Zip Strings Example code

Zip Strings Example

console.log(zipStrings("abc", "123")); // "a1b2c3"

console.log(zipStrings("abc", "1")); // "a1bc"

console.log(zipStrings("a", "123")); // "a123"

console.log(zipStrings("", "123")); // "123"

console.log(zipStrings("abc", "")); // "abc"
