Fix a bug with the CSS nesting transform (#3648)
This release fixes a bug with the CSS nesting transform for older browsers where the generated CSS could be incorrect if a selector list contained a pseudo element followed by another selector. The bug was caused by incorrectly mutating the parent rule's selector list when filtering out pseudo elements for the child rules:
/* Original code */ .foo { &:after, & .bar { color: red; } }/* Old output (with --supported:nesting=false) */ .foo .bar, .foo .bar { color: red; }
/* New output (with --supported:nesting=false) */ .foo:after, .foo .bar { color: red; }
Constant folding for JavaScript inequality operators (#3645)
This release introduces constant folding for the
< > <= >=operators. The minifier will now replace these operators withtrueorfalsewhen both sides are compile-time numeric or string constants:// Original code console.log(1 < 2, '🍕' > '🧀')// Old output (with --minify) console.log(1<2,"🍕">"🧀");
// New output (with --minify) console.log(!0,!1);
Better handling of
__proto__edge cases (#3651)JavaScript object literal syntax contains a special case where a non-computed property with a key of
__proto__sets the prototype of the object. This does not apply to computed properties or to properties that use the shorthand property syntax introduced in ES6. Previously esbuild didn't correctly preserve the "sets the prototype" status of properties inside an object literal, meaning a property that sets the prototype could accidentally be transformed into one that doesn't and vice versa. This has now been fixed:// Original code function foo(__proto__) { return { __proto__: __proto__ } // Note: sets the prototype
