Seeking the most effective method in JavaScript (ES6) to accomplish this task.
Let's consider a 2D array as shown below:
const two_dimensional_array = [
[33000, 100],
[33500, 200],
]
Now, we have another 2D array like this:
const another_array = [
[33500, 1300]
]
The objective is to locate the first value from another_array within two_dimensional_array and then add the second value to it. As a result, the updated two_dimensional_array would look like this:
const two_dimensional_array = [
[33000, 100],
[33500, 1500],
]
