Convert function from variadic

OSCC · JavaScript, Function · Jun 13, 2021

Takes a variadic function and returns a function that accepts an array of arguments.

• Use a closure and the spread operator (...) to map the array of arguments to the inputs of the function.

const spreadOver = fn => argsArr => fn(...argsArr);

const arrayMax = spreadOver(Math.max);
arrayMax([1, 2, 3]); // 3
