The noble Brutus \ 35 Hath told you Caesar was ambitious; \ 36 If it were so, it was a grievous fault, \ 37 And grievously hath Caesar answer'd it. \ 38 Here, under leave of Brutus and the rest- \ 39 For Brutus is an honorable man; \ 40 So are they all, all honorable men- \ 41 Come I to speak in Caesar's funeral. \ 42 He was my friend, faithful and just to me; \ 43 But Brutus says he was ambitious, \ 44 And Brutus is an honorable man. \ 45 He hath brought many captives home to Rome, \ 46 Whose ransoms did the general coffers fill. \ 47 Did this in Caesar seem ambitious? \ 48 When that the poor have cried, Caesar hath wept; \ 49 Ambition should be made of sterner stuff: \ 50 Yet Brutus says he was ambitious, \ 51 And Brutus is an honorable man. \ 52 You all did see that on the Lupercal \ 53 I thrice presented him a kingly crown, \ 54 Which he did thrice refuse. Was this ambition? \ 55 Yet Brutus says he was ambitious, \ 56 And sure he is an honorable man. \ 57 I speak not to disprove what Brutus spoke, \ 58 But here I am to speak what I do know. \ 59 You all did love him once, not without cause; \ 60 What cause withholds you then to mourn for him? \ 61 O judgement, thou art fled to brutish beasts, \ 62 And men have lost their reason. Bear with me; \ 63 My heart is in the coffin there with Caesar, \ 64 And I must pause till it come back to me."; 65 66var replaced = string.replace(/\b\w+\b/g, function() { return "foo"; }); 67for (var i = 0; i < 3; i++) { 68 assertEquals(replaced, 69 string.replace(/\b\w+\b/g, function() { return "foo"; })); 70} 71 72// Check that the result is in a COW array. 73var words = string.split(" "); 74assertEquals("Friends,", words[0]); 75words[0] = "Enemies,"; 76words = string.split(" "); 77assertEquals("Friends,", words[0]); 78
