JavaScript Array find() Method (original) (raw)
Last Updated : 1 Jun, 2026
The find() method in JavaScript looks through an array and returns the first item that meets a specific condition you provide. If no item matches, it returns undefined. It skips any empty space in the array and doesn’t alter the original array.
**Syntax:
array.find(function(currentValue, index, arr), thisArg)
**Parameters:
- **function(currentValue, index, arr): A function to execute on each value in the array until the first element satisfying the condition is found. It takes three parameters:
- **currentValue: The current element being processed in the array.
- **index (optional): The index of the current element being processed in the array.
- **arr (optional): The array find() was called upon.
- **thisValue (optional): A value to use as this when executing the callback function.
**Return value:
- It returns the array element value if any of the elements in the array satisfy the condition, otherwise, it returns undefined.

// Printing desired values. console.log(found);
`
**Example 2: Find the first element greater than 20.
JavaScript `
// Input array contain some elements. let array = [10, 20, 30, 40, 50];
// Method (return element > 20). let found = array.find(function (element) { return element > 20; });
// Printing desired values. console.log(found);

JavaScript `
// Input array contain some elements. let array = [2, 7, 8, 9];
