And execCommand() is depreciated, now no such easy alternative or method to do this

And if u want to use other than execCommand();

u need to start to know

the function as follows;

window.getSelection(),window.getSelection().anchorNode,document.createRange (),

document.createRange ().selectNode (window.getSelection().anchorNode), etc...
