When tracing out variables in the console, How to create a new line?
You should include it inside quotes '\n', See below,
console.log('roleName = '+roleName+ '\n' + 'role_ID = '+role_ID+ '\n' + 'modal_ID = '+modal_ID+ '\n' + 'related = '+related);
In ES6/ES2015 you can use string literal syntax called template literals. Template strings use backtick character instead of single quote ' or double quote marks ". They also preserve new line and tab
const roleName = 'test1';const role_ID = 'test2';const modal_ID = 'test3';const related = 'test4'; console.log(` roleName = ${roleName} role_ID = ${role_ID} modal_ID = ${modal_ID} related = ${related}`);
