Expand description

Extension methods for Expr.

Note that many types implements Into<Expr> and you can do like

use swc_ecma_utils::ExprFactory;

let _args = vec![0f64.as_arg()];

to create literals. Almost all rust core types implements Into<Expr>.

Provided Methods

Creates an ExprOrSpread using the given Expr.

This is recommended way to create ExprOrSpread.

Example
use swc_common::DUMMY_SP;
use swc_ecma_ast::*;
use swc_ecma_utils::ExprFactory;

let first = Lit::Num(Number {
    span: DUMMY_SP,
    value: 0.0,
    raw: None,
});
let _args = vec![first.as_arg()];

Creates an expression statement with self.

Creates a binary expr $self ===

Creates a binary expr $self $op $rhs
