title: Create a Method on an Object
---
## Create a Method on an Object
### Method:
An objects function must be initialised within the object itself. This is demonstrated in the following code.
```javascript
let obj = {
property1 = 1,
function1: function() {
//Code to be exectued
}
};
```
### Solution:
```javascript
let dog = {
name: "Spot",
numLegs: 4,
sayLegs: function() {
return "This dog has " + dog.numLegs + " legs.";
}
};
dog.sayLegs();
```
