1011 - An element access expression should take an argument.

🔍 Regex Patterns

regexFind: /(\w+(?:\([^)]*\))?)\[\]/
regexReplace: $1[index]

💡 Suggestion

Add an index or property name inside the square brackets for element access

📝 Examples

Example 1: Empty array access

- const value = arr[]
+ const value = arr[0]

Explanation: Array access requires an index inside the brackets

Example 2: Empty object property access

- const prop = obj[]
+ const prop = obj['name']

Explanation: Object property access requires a property name inside the brackets
