Front End Web Development Techdegree Student 6,148 PointsStrange error code
I have the first line of the text exactly wrong written as in the video and received the following error message. I took a screenshot but can't shore.
•Uncaught TypeError: Cannot read properties of null (reading 'clientWidth') at terminal.js:108:35 at window. doResize (terminal.js: 45:16) at r.<anonymous> (terminal.js:27:5) at r.emit (index.js: 83:1) at r.emit (index.js: 83:1) at r.onconnect (index.js: 83:1) at r.onpacket (index.js:83:1) r. canonymous> (index.js: 83:1) at r.emit (index.js:83:1 at r.ondecoded (index.js: 83:1) © • Uncaught TypeError: Cannot read properties of null (reading 'clientwidth')
terminal.js: 108
My missing quote marks are not detected. Here is the snapshot. I know it's only the first line but the error should be detected. https://w.trhou.se/7nnpevd21b
When I click on terminal.js:108 at the far right it takes me to sources and this is what I see:
return function (term) { var testChar = getTestChar (); var container = term.element.offsetParent; return { cols: Math. floor(container.clientwidthAntestchar.aftsetwidthing rows: Math. floor (container. clientHeight / testChar.offsetHeight) }; };
What does this mean?

I get a different response when I run the snapshot. The problem I see is caused by a missing quote mark:
alert(Hello, world!"); // current code, missing "
alert("Hello, world!"); // but should be this
