The RegExp \t Metacharacter in JavaScript is used to find the tab character. If it is found it returns the position else it returns -1.
let str = "GFG\t@_123_$";
let regex = /\t/;
let match = str.search(regex);
if (match == -1) {
console.log("No tab character present. ");
} else {
console.log("Index of tab character: " + match);
}
Output
Index of tab character: 3
Syntax:
/\t/
// or
new RegExp("\\t")
