→Added ES5 Array.forEach()
Line 948:
=={{header|JavaScript}}==
This works for any object, as well as arrays. It iterates over the keys of an object.▼
For arrays in ES5, we can use Array.forEach():
<lang JavaScript>"alpha beta gamma delta".split(' ').forEach(
function (x) {
console.log(x);
}
);</lang>
Output:
<pre>alpha
beta
gamma
delta</pre>
▲
<lang JavaScript>for (var a in o) {
print(o[a]);
