Just a shorthand recommendation.
Checking for if(found) { will check for not null and not undefined .
So no need to explicitly use if (found !== null) {

The search return value can only be null or a Node, hence the implicit check.

 search(val) {
 if (this.value === val) {
 return this
 } else if (val < this.value && this.left !== null) {
 return this.left.search(val)
 } else if (val > this.value && this.right !== null) {
 return this.right.search(val)
 }
 return null
 }
