"extend" in javascript code example
Example 1: extend javascript
function extend(object1, ...object2) {
let mergedObject = Object.assign(object1, ...object2);
console.log(mergedObject);
return mergedObject;
}
Example 2: javascript extend array
The .push method can take multiple arguments. You can use the spread operator to pass all the elements of the second array as arguments to .push:
>>> a.push(...b)
If your browser does not support ECMAScript 6, you can use .apply instead:
>>> a.push.apply(a, b)
Or perhaps, if you think it's clearer:
>>> Array.prototype.push.apply(a,b)
