I can see three ways around this: Use template strings like they were designed to be used, without any format function: console.log(`Hello, ${“world”}. This is a ${“test”}`); // might make more sense with variables: var p0 = “world”, p1 = “test”; console.log(`Hello, ${p0}. This is a ${p1}`); or even function parameters for actual deferral of … Read more
Your regex variable is a String. To make it a RegExp, use a RegExp constructor: const regex = new RegExp(String.raw`pattern_as_in_regex_literal_without_delimiters`) For example, a regex literal like /<\d+>/g can be re-written as const re = RegExp(String.raw`<\d+>`, ‘g’) // One \ is a literal backslash const re = RegExp(`<\\d+>`, ‘g’) // Two \ are required in a … Read more
JavaScript template literals require backticks, not straight quotation marks. You need to use backticks (otherwise known as “grave accents” – which you’ll find next to the 1 key if you’re using a QWERTY keyboard) – rather than single quotes – to create a template literal. Backticks are common in many programming languages but may be … Read more
Why are template strings not allowed as literal object keys? Template strings are expressions, not literals1. You can only use string literals (and identifiers) for property names, for everything else – that is not known to be static – you need a computed property name. Is it for performance reasons? No, that’s unlikely. It’s to … Read more
Explanation template literals use the toString() method which by default joins the returned array by map with a ,. To avoid this “problem” you can use join(”) Code var description = [ ‘HTML & CSS’, ‘Javascript object-oriented programming’, ‘Progressive Web apps (PWAs)’, ‘Website Performance Optimization’, ‘Webpack and Gulp workflows’, ‘Fullstack React.js’, ‘Web Components’, ‘Responsive web … Read more
It is called Tagged Template in ES-6 more could be read about them Here, funny I found the link in the starred section of the very chat. But the relevant part of the code is below (you can basically create a filtered sort). function tag(strings, …values) { assert(strings[0] === ‘a’); assert(strings[1] === ‘b’); assert(values[0] === … Read more
To make these literals work like other template engines there needs to be an intermediary form. The best way to do this is to use the Function constructor. const templateString = “Hello ${this.name}!”; const templateVars = { name: “world” } const fillTemplate = function(templateString, templateVars){ return new Function(“return `”+templateString +”`;”).call(templateVars); } console.log(fillTemplate(templateString, templateVars)); As with … Read more
If you introduce a line continuation (\) at the point of the newline in the literal, it won’t create a newline on output: const text = `a very long string that just continues\ and continues and continues`; console.log(text); // a very long string that just continuesand continues and continues
