Javascript

Please utilize the following information when developing for the A32NX to keep your JavaScript functions clean.

Tips and Tricks

Don't use eval

Just don't.

Don't reassign function parameters

function foo(bar) {
  bar = 1; // no!
}

Don't add or remove properties from objects

delete obj.x; // no!

const obj = { y: 1 };
obj.x = 2; // no!

class X {
  constructor() {
    this.y = 1;
  }

  method() {
    this.x = 2; // no!
  }
}

Use specific methods over generic loops where possible

Do not:

// no!
for (const item of array) {
  // ...
}

Do:

// yes!
array.forEach((item) => {
});

Don't create arrays with holes

// no!
const array = new Array(5).fill(0);
// yes!
let array = Array.from({ length: 5 }, () => 0);

Use strict equality

// no!
a == b;
// yes!
a === b;
