javascript - Property 'width' does not exist on type 'HTMLElement' -

the following typescript fails compile:

let svg = document.createelement("svg"); svg.width = 300; 

due error property 'width' not exist on type 'htmlelement'. if change svg canvas, example, compile, it's svgs seems...

any ideas?

let svg = document.createelement("svg"); doesn't create svg element, custom html element.

proper way create svg element:

let svg = document.createelementns("http://www.w3.org/2000/svg", "svg"); 

const customsvg = document.createelement("svg")  const propersvg = document.createelementns("http://www.w3.org/2000/svg", "svg")    console.log(customsvg instanceof svgsvgelement) // false  console.log(propersvg instanceof svgsvgelement) // true    console.log(customsvg.width) // undefined  console.log(propersvg.width) // svganimatedlength {}
