Can someone assist me in resolving an error in my code?
export class BSPTree {
leaf: Box;
lchild: undefined;
rchild: undefined;
constructor(leaf: Box){
this.leaf = leaf;
}
getLeafs(){
if (this.lchild === undefined && this.rchild === undefined)
return [this.leaf]
else
return [].concat(this.lchild.getLeafs(), this.rchild.getLeafs())
}
I'm puzzled as to why this error keeps occurring. Any insights?
It is essential to clearly define the types of lchild and rchild in order to handle cases where they may be undefined.
class BSPTree {
leaf: Box;
lchild: undefined | BSPTree; // This is where we specify
rchild: undefined | BSPTree; // And here as well
constructor(leaf: Box){
this.leaf = leaf;
}
getLeafs(){
if (this.lchild === undefined && this.rchild === undefined)
return [this.leaf]
else
return [].concat(this.lchild?.getLeafs() || [], this.rchild?.getLeafs() || []) // What about here?
}
