split splice
const test = str.split('_').splice(0,1)[0]; const test1 = str1.split('_').splice(0,1)[0]; const test2 = str2.split('_').splice(0,1)[0]; const test3 = str3.split('_').splice(0,1)[0];
split [0]
const test = str.split('_')[0]; const test1 = str1.split('_')[0]; const test2 = str2.split('_')[0]; const test3 = str3.split('_')[0];
match
