Use native ES5 Array prototype methods instead of jQuery

Replace

• $.each( array, function ( index, value ) { ... } ) by array.forEach( function ( value ) { ... } )

• $.grep( array, function ( value ) { ... } ) by array.filter( function ( value ) { ... } )

• $.map( array, function ( value ) { ... } ) by array.map( function ( value ) { ... } )
