camelcaseKeys({'foo-bar': true});
//=> {fooBar: true}
// Convert an array of objects
camelcaseKeys([{'foo-bar': true}, {'bar-foo': false}]);
//=> [{fooBar: true}, {barFoo: false}]
camelcaseKeys({'foo-bar': true, nested: {unicorn_rainbow: true}}, {deep: true});
//=> {fooBar: true, nested: {unicornRainbow: true}}
camelcaseKeys({a_b: 1, a_c: {c_d: 1, c_e: {e_f: 1}}}, {deep: true, stopPaths: ['a_c.c_e']}),
//=> {aB: 1, aC: {cD: 1, cE: {e_f: 1}}}
// Convert object keys to pascal case
camelcaseKeys({'foo-bar': true, nested: {unicorn_rainbow: true}}, {deep: true, pascalCase: true});
//=> {FooBar: true, Nested: {UnicornRainbow: true}}
const camelcaseKeys = require('camelcase-keys');
const argv = require('minimist')(process.argv.slice(2));
