JavaScript: Functional Programming for JavaScript Developers

A matter of style

Like the previous chapters, we will spend some time discussing the style considerations while creating arrays.

• Use the literal syntax for array creation:

  // bad
  const items = new Array();
  // good
  const items = [];

• Use Array#push instead of a direct assignment to add items to an array:

  const stack = [];
  // bad
  stack[stack.length] = 'pushme';
  // good
  stack.push('pushme');
