An isosceles triangle is a triangle with two sides of equal length. To find an isosceles triangle in JavaScript, you need to write a function that takes the lengths of the sides of a triangle as input and returns `true`

if the triangle is isosceles and `false`

otherwise.

Here’s an example that demonstrates how to find an isosceles triangle:

```
function isIsoscelesTriangle(a, b, c) {
return a === b || b === c || a === c;
}
const result = isIsoscelesTriangle(3, 3, 2);
console.log(result);
/*
Output:
true
*/
```

In this example, the `isIsoscelesTriangle`

function takes the lengths of the sides of a triangle as input and returns `true`

if any two sides are equal, which means the triangle is isosceles. If none of the sides are equal, the function returns `false`

, which means the triangle is not isosceles.
