hey lucideer, I think it's usefull when you had to work with SVG sprites + React.
Converts the attributes not supported in React (xlink:href, fill-rule, etc.) to valid React attributes and also in case you have inline styles (eg. style="margin-left:20px") this tool will generate a Javascript object from that style ({marginLeft: 20}), which is valid React inline style.
Also, I think it's super usefull in case you had to use an inline SVG exported from Sketch or AI
