How to Create Dynamic Variable Names in a Loop for Google Maps?

Creating Dynamic Variable Names in a Loop

While working with an Ajax Google Maps script, the need may arise to create dynamic variable names within a loop. Consider the following code:

for (var i = 0; i < coords.length; ++i) {
    var marker+i = "some stuff";
}

The goal is to create variables named marker0, marker1, and so on. However, the code generates a syntax error in Firebug, highlighting a missing semicolon before the statement.

Solution: Using an Array

The recommended approach in this scenario is to leverage an array to store the dynamic variables. Arrays are ordered data structures that can hold multiple values, making them well-suited for situations like this.

Here's the modified code using an array:

var markers = [];
for (var i = 0; i < coords.length; ++i) {
    markers[i] = "some stuff";
}

In this code, an array named markers is created. Within the loop, each element of the array is assigned the value "some stuff." As a result, we obtain an array where each index corresponds to a specific dynamic variable name, e.g., markers[0] represents marker0.
