It doesn't work because in your test string there is no ; however regexp expects one. Just make it optional with ?:

var pattern = /console\..*?\(.*?\);?/gm;

Also make sure the match is not greedy with .*?.

Check the test demo below.

var str = "some string console.log('test'); and console.log(123) \
console.log('123', 12, 'asd'); \
test";

alert( str.replace(/console\..*?\(.*?\);?/gm, '') );
