Can you change a complete language except js,?

as detailed in the title:

recently, I have been working on a react project, which gives me the biggest impression of bug, and complexity. As long as the tester wants to test, the product is ideally dotted everywhere, there will always be bug, the feeling is endless, which makes me begin to doubt the language js.

for the problem, of course, I think of the most perfect solution, but in the js language, I feel that I can"t do it. whether it"s page interaction logic, data logic, business scenario logic, react operation principle and the completeness of public component encapsulation, I can never fully consider the complexity, so I can only solve the problem temporarily and immediately, because, There is bug because of what scenarios and logic can not be considered.

modifying bug, in such a scene every day makes me feel like walking on thin ice, and I don"t want to go on this endless bug.

it is true that great progress has been made in front-end development, with front-end separation, single-page applications, data logic processing transferred to the front-end, or page interaction, or user experience, along with the complexity of front-end development. The same project is equipped with the same number of front and rear developers, but it always feels like there is an endless bug, in the front end while the back end is idle. I don"t know whether we are too weak as the front end or too strong in the back end.

in view of this, I began to doubt the language js. For a weakly typed language, there are already a lot of uncertain and difficult internal conversion rules that are difficult to understand. As for this law, maybe I know too little, or the js routine is too deep. Anyway, I fell into the hole easily.

as for personal development, I am also a relative pursuit of perfection, and I hope to use the most perfect solution to the problem as much as I can. From the very beginning, I chose the front end from scratch. If possible, I would like to change a language that can match my character.

what do you think, or is it a good suggestion?

$('-sharpsomeButton').on('click', function() { let name = $('-sharpname').value() let user = $('-sharpuser').value() // Some other data if(!user) { alert('User must be specified!') return } // Some other checks before sending the request $.ajax({ url: '/', method: 'POST', data: { name, user, ... }, success: data => { if(data.status != 'success' || !(data.msg)) { // Exception handling } $('someDiv').html(data.msg) }, error: (xhr, errMsg, err) => { switch(xhr.response) { case 'INVALID_FORM': // ... case 'TEMPORARY_UNAVAILABLE': // ... default: { switch(xhr.status) { case 400: // ... case 500: // ... // Exception handling } } } } }) })

const API_URL = { someFeature: '/' } async function someAPIFunction(name, user, /* ... */) { let res try { res = await post(API_URL.someFeature, { name, user, /* ... */ }) } catch(err) { throw new Error(err) } switch(await res.text()) { case 'SUCCESS': return // Some other cases } } $('-sharpsomeButton').on('click', async function() { let name = $('-sharpname').value() let user = $('-sharpuser').value() // Some other data if(!user) { alert('User must be specified!') return } // Some other checks before sending the request try { await someAPIFunction(name, user) } catch(err) { // Some exception handling } })
