Flowchart to JavaScript

Why JavaScript

JavaScript runs in every web browser, so the code B4Coder writes runs as it is: paste it into your browser's console. It's the language of websites and web apps.

About the code B4Coder writes: Runs just like your flowchart. Try it in your browser's console.

How each block becomes JavaScript

The most common blocks, and the JavaScript they turn into. View Code uses your own names and values.

age = Number(prompt("How old are you?"));

console.log("Hello, " + name);

let total = 0;

if (age >= 18) {
  ...
} else {
  ...
}

for (let i = 0; i < 10; i++) {
  ...
}

while (total < 100) {
  ...
}

Worked examples: flowchart to JavaScript

Each one is a flowchart in B4Coder. This is the JavaScript it turns into, exactly as View Code writes it.

1let a, b, sum;2
3a = Number(prompt("What is the first number?"));4b = Number(prompt("What is the second number?"));5sum = a + b;6console.log("The sum is " + sum);

1let number;2
3number = Number(prompt("Enter a number"));4if (number % 2 === 0) {5  console.log("It is an Even number");6} else {7  console.log("It is an Odd number");8}

1let count;2
3count = 1;4for (let i0 = 0, n0 = 10; i0 < n0; i0++) {5  console.log("Count: " + count);6  count = count + 1;7}
