EL expression in js function on jsp page

Can I use el expressions in js functions that are on jsp page? I have tried to do so, but the jsp compiler was always complaining that == symbol is not allowed here:

function somefunction() {
  var booleanExpression = '${myBean.a == -1}';
  ....
}

myBean is a request scope attribute that has an integer property a. I also have tried to use eq instead of ==, but the error remains the same and that is weird.

I want my boleanExpression to be true or false in result.

Leave off the quotes.

var booleanExpression = ${myBean.a == -1};

JSP will dump out either true or false, with either of which JavaScript will be perfectly happy.
