Uncaught SyntaxError: Unexpected token '{'

The error is in the first line, i have been staring at it forever and cant find the problem.

bfs() {
    let result = []
    let queue = []

    queue.push(this.root)

    while(queue.length) {
      let currentNode = queue.shift()

      result.push(currentNode.value)

      if (currentNode.left) {
        queue.push(currentNode.left)
      }
      if (currentNode.right) {
        queue.push(currentNode.right)
      }
    }

    return result
  }
}

bf(){

}

the above syntax is only valid within the scope of an ES6 class definition or an object literal.

for an object literal

const baz ={
     name:"foo",
     bar(){
      //do anything
    }
}

for an ES6 class

class baz {
   bar(){
     //do something
   }
}

any use outside of the above will result in syntax error,

bar(); //a function call

the above code is used to call or invoke a function. To create or define a function, the syntax below are valid

 function bar(){
    //do something
  }
  const baz = ()=>{
    //do something
   }
  const foo = function(){
   //do something
}

 (function(){
  //do something
 })() //immediately invoked function
