Subject is like any other entity, you can use web api to create it.

function createSubject() {

    var serverURL = Xrm.Page.context.getClientUrl();
    var subject = {};
    subject["title"] = "test subject"; 
    subject["featuremask"] = 1;

    //subject["parentsubject@odata.bind"]="/subjects(<GUID without Quotes>)";  //setting existing lookup

    subject["parentsubject"] = {
        "title": "test parent subject",
        "description": "deep insert to add parent before child",
        "featuremask": 1  
    };

    var req = new XMLHttpRequest();
    req.open("POST", serverURL + "/api/data/v8.2/subjects", true);
    req.setRequestHeader("Accept", "application/json");
    req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    req.setRequestHeader("OData-MaxVersion", "4.0");
    req.setRequestHeader("OData-Version", "4.0");
    req.onreadystatechange = function() {
        if (this.readyState == 4 /* complete */ ) {
            req.onreadystatechange = null;
            if (this.status == 204) {
                var subjectUri = this.getResponseHeader("OData-EntityId");
            } else {
                var error = JSON.parse(this.response).error;
                alert(error.message);
            }
        }
    };
    req.send(JSON.stringify(subject));
}
