<\/span><\/h2>\nWhen you want to append a value to an array in JavaScript, you have a few different options. One common method is to use the push()<\/code> method, which adds one or more elements to the end of an array and returns the new length of the array. Here’s an example:<\/p>\n“`javascript
\nlet myArray = [1, 2, 3];
\nmyArray.push(4);
\nconsole.log(myArray); \/\/ Output: [1, 2, 3, 4]
\n“`<\/p>\n
Another option is to use the array’s length property to determine the next index and assign a value to that index. For example:<\/p>\n
“`javascript
\nlet myArray = [1, 2, 3];
\nmyArray[myArray.length] = 4;
\nconsole.log(myArray); \/\/ Output: [1, 2, 3, 4]
\n“`<\/p>\n
