E0712: missing ',' between array elements
This error occurs when there is a missing comma (',') between elements in an array declaration or initialization. In JavaScript, commas are used to separate individual elements within an array, and the absence of a comma will lead to a syntax error.
let myArray = [1 2 3];
To fix this error, you need to add a comma between each element within the array declaration or initialization
let myArray = [1, 2, 3];
