Answering normajeans' question about setting default value. Create a defaults object with same properties and merge with the arguments object

If using ES6:

    function yourFunction(args){
        let defaults = {opt1: true, opt2: 'something'};
        let params = {...defaults, ...args}; // right-most object overwrites 
        console.log(params.opt1);
    }

Older Browsers using Object.assign(target, source):

    function yourFunction(args){
        var defaults = {opt1: true, opt2: 'something'};
        var params = Object.assign(defaults, args) // args overwrites as it is source
        console.log(params.opt1);
    }
