How to read a local image file in javascript? [duplicate]

I am reposting this question, don’t mark as duplicate. this is not duplicate of this question

I have a JSON

MyJson = {name:"file1",path:"d://photos/photo.jpg"}

I want to get photo.jpg in a const variable

const file: File = MyJson.path;

I want to perform multiple operations on file. If i can read it as dataURL then also that is fine. Please help me
How can i do this using javascript or angular?
