コントラクト

• findIndex matches elements using property path strings, key-value pairs, or partial objects, applies fromIndex offsets, and returns -1 for unfound items or nil collections.
• export identity matches between es-toolkit/compat named export and es-toolkit/compat/findIndex default export
• property name strings match the first item with a truthy value at the specified property or nested path
• two-element arrays match items where the property key equals the expected value
• plain objects perform deep partial matching against collection items
• omitting the predicate defaults to identity matching the first truthy element
• fromIndex offsets start searching from the given index, truncating floats and interpreting negative values from the array end
• null and undefined collections safely return -1 without throwing errors
• array-like objects and strings are converted and searched identically to arrays
