conforms
INFO
This function is only available in es-toolkit/compat for compatibility reasons. It either has alternative native JavaScript APIs or isn’t fully optimized yet.
When imported from es-toolkit/compat, it behaves exactly like lodash and provides the same functionalities, as detailed here.
Creates a function that invokes the predicate properties of source with the corresponding property values of a given object, returning true if all predicates return truthy, else false.
Note: The created function is equivalent to conformsTo with source partially applied.
Signature
typescript
function conforms(source: Record<PropertyKey, (value: any) => boolean>): (object: Record<PropertyKey, any>) => boolean;Parameters
source(Record<PropertyKey, (value: any) => boolean>): The object of property predicates to conform to.
Returns
((object: Record<PropertyKey, any>) => boolean): Returns the new spec function.
Examples
typescript
const isPositive = n => n > 0;
const isEven = n => n % 2 === 0;
const predicates = { a: isPositive, b: isEven };
const conform = conforms(predicates);
console.log(conform({ a: 2, b: 4 })); // true
console.log(conform({ a: -1, b: 4 })); // false
console.log(conform({ a: 2, b: 3 })); // false
console.log(conform({ a: 0, b: 2 })); // false
