Camel case a string. Explicitly adds a single underscore between groups of numbers to maintain readability and reversibility (E.g. 1.20.5 becomes 1_20_5, not 1205), by default.

Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a toString property, numbers and booleans. Empty values (null and undefined) will result in an empty string.

npm install camel-case --save

var camelCase = require('camel-case')

camelCase('string')         //=> "string"
camelCase('dot.case')       //=> "dotCase"
camelCase('PascalCase')     //=> "pascalCase"
camelCase('version 1.2.10') //=> "version_1_2_10"

camelCase('STRING 1.2', 'tr') //=> "strıng_1_2"

camelCase('string 1 2 3', null, true) //=> "string123"

Includes a TypeScript definition.
