Which languages, frameworks etc to use for an app

Hello

I’m wanting to create a new web app which will be data heavy (perhaps 10’s thousands of database entries or more). These will be stored in a databse and then analysed/sorted reviewed etc back-end, before being displayed to the user on tables and or maps depending on which filters are selected.

I’ve coded in php and javascript before but have not branched out to any frameworks. Could someone recommend a good selection to use which I can start learning.

Thanks
