# Index Signature A type in TypeScript usually describes an exact set of fields to match on an object. An index signature is a way to define the Shape of fields which are not known ahead of time.

The error "Property is incompatible with index signature" occurs when a property is not compatible with the specified type of the index signature. To solve the error, change the type of the property or use a union to update the type in the index signature.

Index Signatures This index signature states that when a StringArray is indexed with a number , it will return a string . Only some types are allowed for index signature properties: string , number , symbol , template string patterns, and union types consisting only of these.

The error "Property is incompatible with index signature" occurs when a property is not compatible with the specified type of the index signature. To solve the error, change the type of the property or use a union to update the type in the index signature.

The index signature can be used to define the type of object whose values are of consistent kinds or whose structure you do not know. The index signature is made up of the index name and types enclosed in square brackets and then followed by a colon and the value type: {[indexName: KeyType]: ValueType}.

The idea of the index signatures is to type objects of unknown structure when you only know the key and value types. An index signature fits the case of the salary parameter: the function should accept salary objects of different structures — just make sure that object values are numbers.

The name of the index signature, for example, index in { [index:string]: { message:string}} For example, if it's usernames, you may do { [username:string]: {message:string}} to assist the next developer who will look at the code (which just might happen to be you).

An index signature parameter type cannot be a literal type or generic type. Consider using a mapped object type instead. We can deal with the above issue by creating multiple index signatures or using the in keyword.
