I'm trying to figure out how to replace a string in dot notation with square brackets:
emergency.1.phone.2
Should convert to:
emergency[1][phone][2]
I'm trying to make it dynamic so it will convert the string regardless of how many dots there are.
You could do this by using the string .replace method with a regex with a special replacement function.
The regex is /\.(.+?)(?=\.|$)/g, which looks for:
., followed by. or the end of the stringThen, you can specify a function which takes the captured string and puts it in brackets, and use that as the replacer.
Example:
const dots = "emergency.1.phone.2"
// Should convert to:
// emergency[1][phone][2]
console.log(dots.replace(/\.(.+?)(?=\.|$)/g, (m, s) => `[${s}]`))
(: +1
const originalString = 'emergency.1.phone.2'
const desiredString = originalString
.split('.')
.reduce((fullPath, arg) => fullPath + `['${arg}']`)
console.log(desiredString)
// logs: emergency['1']['phone']['2']
An alternative is using the function reduce.
let str = "emergency.1.phone.2",
arr = str.split('.'),
result = arr.reduce((a, s, i) => i === 0 ? s : a + `[${s}]`);
console.log(result);.as-console-wrapper { max-height: 100% !important; top: 0; }
emergency['1']['phone']['2']? ... but what do you mean with dynamic? Explain a little bit more.
