JavaScript Error: 'toRaw(...)[key].apply is not a function' - Fixing Array Push Issue

The error 'TypeError: toRaw(...)[key].apply is not a function' arises when you incorrectly attempt to use the 'push' method on an array. Specifically, you are likely assigning a value to the 'push' method instead of calling it with parentheses.

To resolve this, modify the line:

series.value[0].data.push = (y)

to:

series.value[0].data.push(y);

This change ensures that the 'push' method is correctly called, adding the 'y' value to the 'series.value[0].data' array.

Here's a breakdown of the issue:

• Incorrect Usage: Assigning a value to 'push' using the assignment operator ('=') treats 'push' as a variable, causing the error because it's not a function.
• Correct Usage: Calling the 'push' method with parentheses and the value to add as an argument ensures it functions correctly.

By making this simple adjustment, you should successfully eliminate the 'TypeError' and ensure proper array manipulation.
