How to create an object/array from a key/value string made up with '/'

Question

Take the following string:

/foo/1/bar/2/cat/bob

I need to parse this into an object or array which ends up being:

foo = 1
bar = 2
cat = bob

Answer 1

 var sample = "/foo/1/bar/2/cat/bob".substring(1); var finalObj = {}; var arr = sample.split('/'); for(var i=0;i<arr.length;i=i+2){ finalObj[arr[i]] = arr[i+1]; } console.log(finalObj); 

Answer 2

 const str = '/foo/1/bar/2/cat/bob/test/' const parts = str.split('/') .filter(val => val !== '') const obj = {} for (let ii = 0; ii < parts.length; ii+=2) { const key = parts[ii] const value = parts[ii+1] obj[key] = !isNaN(value) ? Number(value) : value } console.log(obj) 

Answer 3

Regular expressions is the tool of choice for all kinds of parsing:

 str = '/foo/1/bar/2/cat/bob' obj = {}; str.replace(/(\\w+)\\/(\\w+)/g, (...m) => obj[m[1]] = m[2]); console.log(obj); 

Answer 4

Just for the fun of it,

let str = "/foo/1/bar/2/cat/bob",
    arr = str.split("/"),
    obj = {};
arr.shift();
while (arr.length) obj[arr.shift()] = arr.shift();
