+// 9. Delete First Character of a String
+
+// The slice() method is frequently used to remove the first character by returning a new string from index 1 to the end.
+{
+  let s1 = "hihello";
+  let s2 = s1.slice(1);
+  console.log(s2);
+}
+
+//Similar to slice(), substring() creates a new string starting from index 1, effectively removing the first character.
+
+{
+  let str = "hihello";
+  let newStr = str.substring(1);
+  console.log(newStr);
+}
+
+// Using Array Destructuring with join()
+
+{
+  let s1 = "hihello";
+  let s2 = [...s1].slice(1).join("");
+  console.log(s2);
+}
+
+// Using replace() with Regular Expression
+
+{
+  let s1 = "hihello";
+  let s2 = s1.replace(/^./, "");
+  console.log(s2);
+}
