Finding SharePoint Item Level Permissions in ECMAScript

In EMAScript, to find out item level permissions in a list/library we don’t have respective

object in CurrentItem which states with Permission Name. Generally if we do the same in

 Server Object Model it returns Permission Names in string format. This ease our task but

in ECMAScript it returns in nvarchar format.

For Example, to know whether item has Read Permission, below is the snippet code.

if (ctx.CurrentItem.PermMask == "0xb008431061") { //This value is for Read Permission

}

else {

}
