Functional JavaScript First StepsWhat is functional programming?Exercise: Pure FunctionsStaying out of the loop with recursionFlying first class with higher-order functionsExercise: Filter, Map, ReduceGetting closureExercise: Closures & CurryingIt's functions all the way downExercise: Function CompositionImmutabilityExercise: Avoiding mutationRecap & takeawaysNext steps
Exercise: Iteration vs. Recursion
function iterativeFactorial(n) {
let product = 1;
while (n > 0) {
product *= n;
n--;
}
return product;
}
iterativeFactorial(3) // Try changing the input to test out the function
function recursiveFactorial(n) {
if (n === 0) return 1;
return n * recursiveFactorial(n - 1);
}
recursiveFactorial(3) // Try changing the input to test out the function
function iterativeFibonacci(n) {
// TODO your code goes here
}
function recursiveFibonacci(n) {
// TODO your code goes here
}
iterativeFibonacci(n)
recursiveFibonacci(n)
Purpose-built for displays of data
Observable is your go-to platform for exploring data and creating expressive data visualizations. Use reactive JavaScript notebooks for prototyping and a collaborative canvas for visual data exploration and dashboard creation.
