I use babel compile src from es6 to es5 with sourceMaps, but I can't get the original position of error.
es6
class index {
add(a, b) {
return a + b;
}
}
let obj = new index();
console.log(obj.addx(1, 2));
es5
"use strict";
function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }
function _defineProperties(target, props) { for (var i = 0; i < props.length; i++) { var descriptor = props[i]; descriptor.enumerable = descriptor.enumerable || false; descriptor.configurable = true; if ("value" in descriptor) descriptor.writable = true; Object.defineProperty(target, descriptor.key, descriptor); } }
function _createClass(Constructor, protoProps, staticProps) { if (protoProps) _defineProperties(Constructor.prototype, protoProps); if (staticProps) _defineProperties(Constructor, staticProps); Object.defineProperty(Constructor, "prototype", { writable: false }); return Constructor; }
var index = /*#__PURE__*/function () {
function index() {
_classCallCheck(this, index);
}
_createClass(index, [{
key: "add",
value: function add(a, b) {
return a + b;
}
}]);
return index;
}();
var obj = new index();
console.log(obj.addx(1, 2));
