GlideRecord

• Use getUniqueValue to get sys_id.
• Use newRecord instead of instantiating to get a new record with default values.
• Dot-walking on GlideRecord returns GlideElement, use getRefRecord to get GlideRecord.

GlideForm

• Use getBooleanValue for boolean fields.

// This is just a handy snippet I use when troubleshooting glide records
// in a background script to quickly see all the properties and values of a glide record
// Just change the table name and query for the glide record to test

var gr = new GlideRecord("<your_table_name>");
gr.addQuery("<field_name>", "<value>");
gr.query();
			
while (gr.next()) {

The -- None -- option may not have a sys_choice record associated with it. 
A choice list field set to -- None -- evaluates to these values, depending on the script context as listed below.
For client-side scripts,such as client scripts: "" (empty string)
For server-side scripts, such as business rules: "0" (string of the number zero)

function (someString) {
  // test string is opened with curly brace or machine bracket
  if (someString.trim().search(/^(\[|\{){1}/) > -1) {
    try { // it is, so now let's see if its valid JSON
      var myJson = JSON.parse(someString);
      // yep, we're working with valid JSON
    } catch (e) {
      // nope, we got what we thought was JSON, it isn't; let's handle it.
    }
  } else {
