Concatenate string with ternary operator in javascript

Question

Its being annoying

Following code :

var arrays = [1,2,3];
alert(\'Array has \' + (arrays.length > 0) ? \'multiple\':\'single\' +         


        

Answer 1

Your first example is parsed this way

alert(('Array has ' + (arrays.length > 0)) ? 'multiple':('single' + ' value'));

given the operator precedence of + is much higher than that of ?:.
