literal-joiner is used for sample join literal json object as array.

installation

npm install npm-literal-joiner

var lj = require('npm-literal-joiner');
// lj(object, separator, maxDepth)

var yourObj = {'a':'b','c':'d'};

// lj(yourObj) = 'abcd'
// lj(yourObj, ',') = 'a,b,c,d'
var obj = {
    'a': 1,
    'b': 2,
    'c': {
        'd': 3,
        'e': 'f'
    },
    'g': 'h'
};

// lj(obj, '', 1) = 'a1b2c{"d":3,"e":"f"}gh'
