You can get string between 2 characters in TypeScript with indexOf() and slice(): find the start character, search for the end character from just after it, and slice the text in between. Here’s the core of it: Nothing below is typed from memory: I saved each example as a .ts file, compiled it in strict … Read more >>
To split a string by dot in TypeScript, call split(“.”). It returns a string[] of the pieces between each period. Pass the plain string “.”, not /./, because an unescaped regex dot matches every character: I ran all of this code through TypeScript 7.0.2 and Node.js v22.22.2 with strict mode on, and the outputs below … Read more >>
You split a string by regex in TypeScript by passing a RegExp to split() instead of a string. Every match becomes a cut point, and you get back a string[]: Each snippet here was compiled in strict mode with TypeScript 7.0.2 and Node.js v22.22.2. I pasted the console output straight from those runs. How split() … Read more >>
You split a string with multiple separators in TypeScript by passing a regular expression to split(). Put single-character separators in a character class like /[,;|]/, and you’ll get back a string[] with one piece per value: All examples were compiled in strict mode with TypeScript 7.0.2 and Node.js v22.22.2, and I pasted the console output … Read more >>
You can get the string after a character in TypeScript by finding the character with indexOf() and passing the next position to slice(). Check for -1 first, because a missing character would otherwise hand you back the whole string: Quick note on setup: strict mode was on for every compile, with TypeScript 7.0.2 and Node.js … Read more >>
You can remove quotes from a string in TypeScript with replaceAll(‘”‘, “”), which deletes every double quote. For single, double and curly quotes at once, use a global regex. When only the wrapping quotes should go, slice them off: My test machine had TypeScript 7.0.2 and Node.js v22.22.2, with –strict switched on, so the output … Read more >>
To split a string by new line in TypeScript, call split(/\r?\n/). The regular expression matches both Unix line breaks (\n) and Windows line breaks (\r\n), and you get back a string[] with one entry per line: Nothing here is made up: tsc compiled each file in strict mode (TypeScript 7.0.2 and Node.js v22.22.2), Node ran … Read more >>
When you need to split a string and get the last element in TypeScript, call split() and read the final item with at(-1). Add ?? “” because TypeScript types that item as string | undefined: I tested all of this on TypeScript 7.0.2 and Node.js v22.22.2, strict mode on. What you see under each example … Read more >>
To convert a string to a double in TypeScript, pass it to Number() or parseFloat(). TypeScript has no separate double type; every number is already a 64-bit double, so “1299.99” becomes 1299.99: My test bench for this one: TypeScript 7.0.2 and Node.js v22.22.2, strict mode on, with each console result below copied from a real … Read more >>
