+//Original code with errors:
+
+// function capitalise(str) {
+//   let str = `${str[0].toUpperCase()}${str.slice(1)}`;
+//   return str;
+// }
 
 // =============> write your explanation here
+// The error occurs because the variable "str" is being declared twice in the same scope. This causes a conflict and results in a syntax error.
+// To fix this error, we can simply remove the "let" keyword when reassigning the value to "str" inside the function. This way we are not declaring a new variable, but rather reassigning the existing parameter "str".

+function capitalise(str) {
