It's just convenient rather than calling the getter/setter in case the
accessed value is non public. Example:
function Editor()
{
var lineNo = 42;
this.getLineNumber = function () {
return lineNo;
};
this.setLineNumber = function (no) {
lineNo = no;
}
}
editor = new Editor;
Object.defineProperty(editor, "lineNumber", {
get: function () {
return this.getLineNumber();
},
set: function (no) {
this.setLineNumber(no);
}
});
console.log(editor.getLineNumber());
console.log(editor.lineNumber);
