$.globalEval in native javascript

eval allows developers to execute code and create variables in the scope in which it is executed. For Example:

function evalExec(){
    eval('var a=10;');
}
evalExec();

When we execute evalExec function a variable is created inside evalExec function's scope.

What do we do when we want the code to be evaluated in the global scope?

jQuery provides a $.globalEval function which executes the code in global scope. If we want to achieve same thing via javascript, we can do it like this -

function globalEvalExec(){
    window.eval.call(window,'var a=10;');
}
globalEvalExec();

This creates a variable a in the global scope and it is accessible via window.a
