Tool usage guide
The Index Of tool finds the position of a specific value within an array using lodash's _.indexOf function. It returns the index where the value is first found, or -1 if not present, supporting various data types and optional search starting points.
Background
An inventory manager has a JSON array of product IDs and needs to find where a specific ID is listed.
Problem
Manually searching through hundreds of entries is inefficient and error-prone.
How to use
Enter the array of product IDs in the Array Input field and the target ID in Search Value.
Outcome
The tool returns the index position, enabling quick access to the product's location in the list.
Background
A data analyst is reviewing survey responses stored in an array to identify repeated answers.
Problem
Need to detect duplicates for data cleaning without scanning the entire array manually.
How to use
Input the array of responses and the value to check, using fromIndex to find subsequent occurrences.
Outcome
By returning the index, the tool helps pinpoint where duplicates appear, aiding in data validation.
It returns -1 to indicate the value was not found.
Yes, it supports various data types including objects and arrays, but ensure inputs are in valid JSON format.
Enter a number to start the search from that index, skipping earlier elements in the array.
The tool can handle arrays of any size, but performance may depend on your browser for very large datasets.
The array must be entered as a valid JSON array, such as [1, 2, 3] or ["a", "b", "c"].
