Question

Below is the function that does some stuff.

ns.Line2Point = function (params) {
        points = params.points;
        // code here
};

In the code above, params object contains a points object. So, when I want to call Line2Point method, I must create a object, and it contain points object. But, I don’t know how to in Javascript. I just have some ideas like the code below, but don’t know it true or false:

    var params;
    var points;
    // some code to initialize for points object
    params.points = points
    ns.Line2Point(params)

Please teach me this. Thanks 🙂

as you said you just need to initialize params.

var params = {};   // initialize to an object literal
params.points = {}; // points is now an object literal, too

if you already have points, initialize params, then do

params.points = points; // assign points to the points property of params
