javascript - js searching for pattern doesnt work -


i used pattern make sure if there running same char 3 occurrence in php code , working when tried in javascript didn't work idea?

if (!(/(.)\\1{2}/.test(string))) {   console.log('there no running 3 chars occur in string'); } else{   console.log('there 3 running same char occur in string'); }

the console give me "here no running 3 chars occur in string" although string "iii"

any idea?

you have escaped \ in pattern. trying match letter followed 2 \ characters. try updating pattern /(.)\1{2}/. 

if (!(/(.)\1{2}/.test(string))){     console.log('there no running 3 chars occur in string'); } else {      console.log('there 3 running same char occur in string'); }
