Tests:

substring
const test = str.substring( 0 ,str.indexOf('_')); const test1 = str1.substring( 0 ,str.indexOf('_')); const test2 = str2.substring( 0 ,str.indexOf('_')); const test3 = str3.substring( 0 ,str.indexOf('_'));
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
const test = str.match(/([\s\S]*)_/)[1]; const test1 = str1.match(/([\s\S]*)_/)[1]; const test2 = str2.match(/([\s\S]*)_/)[1]; const test3 = str3.match(/([\s\S]*)_/)[1];
