Function Helpers
Utility functions for working with function operations.
Functions
Section titled “Functions”| Function | Description |
|---|---|
compose |
Composes functions right-to-left: `compose(f, g)(x)` is equivalent to `f(g(x))`. |
createCachedResolver |
Creates a lazy, cached resolver: `resolve(key)` computes and caches `compute(key)` the first time a given key is seen, … |
curry |
Transforms a multi-argument function into a chain of single-argument functions (Haskell-style currying). |
debounce |
Creates a debounced function that delays invoking func until after delay milliseconds have elapsed since the last time … |
flip |
Creates a function that invokes `fn` with the first two arguments swapped. |
identity |
Returns the given value unchanged Useful as a default transform, in function composition, or as a placeholder mapper. |
memoize |
Returns a memoized version of the function that caches results. |
negate |
Creates a function that negates the result of `predicate`. |
noop |
A no-operation function that does nothing and returns `undefined` Useful as a default callback, placeholder, or to exp… |
once |
Creates a function that is restricted to be called only once. |
partial |
Partially applies arguments to a function, returning a new function that accepts the remaining arguments. |
pipe |
Composes functions left-to-right: the output of each function is passed as input to the next. |
returnOrThrowError |
Return a value or throw an error if null or undefined. |
throttle |
Creates a throttled function that only invokes func at most once per every wait milliseconds |
unary |
Creates a function that calls `fn` with only its first argument, discarding any others. |
