About General Purpose Javascript (ECMA) Syntax? [SOLVED]

[Joseph1916]

To all;

OS = Ubuntu Linux 22.04
QCAD = 3.28.1

I have begun coding for a coordinate Geometry program (COGO), and the first thing I noted was ECMA implementation of JavaScript is it dose not recognize General Purpose JavaScript Keywords, such as an assignment command such as "let", as in let x = 1.5....

The objective is to create a large 2d array of point#, x, y, z, descriptions.....

Can that observation be commented on ??

You can use var instead of the scoped let which is not supported by Qt Script (Qt 5).

QJSEngine (Qt 6) has some support for let as far as I know.

Joseph1916, You asked that already and it was answered.

The reserved term "var" appears in in some of my snippets

Correct, var is the most common way to declare variables.
One should always declare variables.

One can use var the same way:

Code: Select all

var myValue = 1.5;

A good idea is to give your variables a meaningful name.

The objective is to create a large 2d array of point#, x, y, z, descriptions.....

Isn't x-y-z a coordinate in 3D?
As input or as output to QCAD?
There is already a script of Andrew for inputting such lists.

Thanks to Andrew and CVH...... var is working fine... I have closed this Topic, and will restart where I left off tomorrow. Thanks...
