Hi All,

Kindly help me on below issue

which is best method to check null / not null Performance wise/ Best Script practice wise.

check assigned_to Empty/Null/:

if(gr.assigned_to==" " && gr.sys_created_by !=gr.opened_by)

if(gr.assigned_to.nil() && && gr.sys_created_by !=gr.opened_by)

if(gs.nil(gr.assigned_to) && gr.sys_created_by !=gr.opened_by)

if(JSUtil.nil(gr.assigned_to) && gr.sys_created_by !=gr.opened_by)

check assigned_to Not Empty/Not Null/:

if(gr.assigned_to!=" " && gr.sys_created_by !=gr.opened_by)

if(!gr.assigned_to.nil() && gr.sys_created_by !=gr.opened_by)

if(!gs.nil(gr.assigned_to) && gr.sys_created_by !=gr.opened_by)

if(JSUtil.notNil(gr.assigned_to) && gr.sys_created_by !=gr.opened_by)

Kindly help me on this, it has to be work for long-lasting .

Greetings!

Use strict equality (===) or strict inequality (!==) where possible, as it not only compares the values but also checks the data types. As this can prevent unexpected results due to type.
JSUtil is not available for scoped apps
Consider readability and maintainability of the code. It's essential to write code that is easy to understand and modify in the future.
I beleive gs.nil() and gs.notNil() are best practice in ServiceNow, as they handle null, empty strings, and undefined variables correctly.

refer below article:

Please hit the thumb and Mark as correct based on Impact!!
