All these answers do NOT take into account that you asked specifically about a DIV element   document querySelector  div the-div-id      see https   developer mozilla org en-US docs Web API Document querySelector

There s an even better solution  You don t even need to check if the element returns null  You can simply do this   if  document getElementById  elementId        console log  exists       That code will only log exists to console if the element actually exists in the DOM

if   document getElementById  given-id        It does not exist     The statement document getElementById  given-id   returns null if an element with given-id doesn t exist  and null is falsy meaning that it translates to false when evaluated in an if-statement   other falsy values

Try getting the element with the ID and check if the return value is null   document getElementById  some nonexistent id       null   If you re using jQuery  you can do       some nonexistent id   length     0
