Arrays in JAVASCRIPT
To create an empty array, we code [
and ]
.
JavaScript
const friends = [];
console.log(friends);
We use commas ,
to separate two or more values in an array, like "Tom"
from "Mia"
.
JavaScript
const friends = ["Tom", "Mia"];
console.log(friends);
Any number of values fits in an array. We add more by coding a comma and then the value.
JavaScript
const friends = ["Tom", "Mia", "Lee"];
console.log(friends);
