I like repeating the `var` token (see http://nodeguide.com/style.html#variable-declarations), but to be consistent you should put the comma at the end of each line, see some lines below, for example at https://github.com/kevinsimper/Crafty/blob/6c8835a650b972874cc22e238f1960f16466e3c0/src/2D.js#L15
