p5.js version

2.3.0

Web browser and version

Brave 1.90.122

Operating system

Linux Mint 22.1

Steps to reproduce this

Steps:

1. Create a 1D vector
2. Set v.x to change the "x" value
3. Show that setting v.x didn't work

Snippet:

function setup() {
  let v = createVector(1);
  v.x = 2;
  
  // This should print "vector[2]", but prints "vector[1]"
  print(v.toString());
}

Problem

The code contains a comparison if (this.values.length > 1); it doesn't work because the length is 1. The comparison should be if (this.values.length > 0).

Start by locating the p5.Vector implementation and the comparison on this.values.length described in the issue. Reproduce the provided createVector(1) snippet, then verify that assigning v.x changes the printed vector from vector[1] to vector[2].
